If...Then...Else

Ribbon groups used The Font group and the Clipboard group on the Home ribbon. You will be creating a worksheet for a shop that sells mirrors. It offers cut-to-size mirrors and they need a worksheet that will provide instant quotes to customers.

Details The shop offers only one thickness of glass, 6mm. It offers a choice of polished, or polished and bevelled edges. The price of the mirror is dependent upon the surface area and the perimeter length. These are the prices: £32 per square metre of surface area £1.70 per linear metre of perimeter for polished edges £2.10 per linear metre of perimeter for polished and bevelled edges

Changing font and size Select cell A1 Change the font size to 26 by clicking the down arrow on the right-hand side of the Font Size list box in the Font group on the Home ribbon. Change the font – choose the one you like from the Font list box. Make the text in cell A1 bold. Move the contents of cell B1 to D1.

Change some more of the headings and formats to look like this: Tip: To copy formatting from a cell or cell range, select the cell(s) containing the formatting you want to copy. Click the Format Painter button in the Clipboard group on the Home ribbon. Click the cell(s) you want to format. All the original cell’s formatting is copied.

Adding the formulae The calculation for Total surface area is Width x Height. What will the formula be? Type the formula =B9*B10 in cell B12. The calculation for Total perimeter length is 2 x (Width + Height). What will the formula be? Type the formula =2*(B9+B10) in cell B13. The calculation for Price for surface area is Total surface area (square metres) x Price per square metre. What will the formula be? Type the formula =B12*B4 in cell D12. Save your changes. Try out the formulae by typing the length and width of a mirror in cells B9 and B10, respectively. Got to here

If statements Type the letter P or PB into cell D9 to specify the mirror’s edges. The calculation for the Price for edges has to include an IF statement because it is conditional on whether they are polished, or polished and bevelled. IF the edges are polished THEN the price for the edges = perimeter length x polished price IF the edges are bevelled THEN the price for the edges = perimeter length x bevelled price

...breaking it down further. IF cell D9 = P THEN cell D13 = B13*B5 IF cell D9 = PB THEN cell D13 = B13*B6 Select cell D13. Click on the Insert Function to the left of the formula bar.

The Insert Function dialogue box is displayed The Insert Function dialogue box is displayed. Select IF from the Select a function: list. If you cannot see it in the list, change the category to Logical. Click OK.

The Function Arguments dialogue box is displayed The Function Arguments dialogue box is displayed. Complete the three IF fields as shown: Click OK

Fill in the last formula for the total price, next to the Instant Quote heading in cell B15. It should be =SUM(D12:D13) Test your spreadsheet by typing 0.5 in cell B9 and 1.2 in cell B10. The Instant Quote should be 24.98

Formulae so far Start here

Now you are going to apply a 10% discount if the quote is £100 or more. Type and format the cells A16 and A17, changing the border around the quote as shown:

You will use the IF statement as before, but this time you need the formula to recognise when the price quoted in cell B15 is more than £99.99. To do this you will use the > operator. The calculation for the Discount is conditional on whether the quoted price is more than £99.99. IF the instant quote is more than £99.99 THEN the discount = instant quote x 10%, OTHERWISE the discount = 0.

Breaking it down further: IF cell B15 > 99.99 THEN B16 = B15*10% OTHERWISE cell B16 = B15*0 Click cell B16 and open the Function Arguments dialogue box as before. Complete the three IF fields using the > operator.

Type the formula =B15-B16 in cell B17 to calculate the final price. Test your spreadsheet model by typing in different widths and lengths, and different types of mirror into the worksheet to see the effect on the final price. Finally, format all the currency cells to show pound signs, set to two decimal places. Does the worksheet work properly?

Your spreadsheet should look like this:

Adding some colour The quote worksheet might look better if it was a bit more colourful. You can do this by changing the font colour and the background fill colour. Changing the font colour: Select cell A1. Click the down-arrow on the Font Colour button in the Font group on the Home ribbon and select a colour.

Changing the background fill colour: With cell A1 still selected, click the down-arrow on the Fill Color button in the Font group on the Home ribbon, select a colour.

Aligning cell content You can set where the text appears in a cell – left, right, top, bottom or centre. Use the Align Right, Align Left and Centre buttons and the Top, Middle and Bottom buttons in the Alignment group on the Home ribbon. You can also use the Format Cells dialogue box, which allows more options (e.g. slanting).

Widen row 1 by clicking and dragging between the row selectors of row 1 and row 2. Select cells A1 and D1 and click the Middle Align button. Cell content orientation Right-click cell A1 and select Format Cells… from the shortcut menu. Select the Alignment tab on the Format Cell dialogue box. Change the orientation of the text by dragging the red dot on the Orientation dial so that the text is slightly slanting. Click OK.

Add some more colours, trying different formatting so that it looks something like this: Save the changes.

Exercise 6 Try to work independently. Follow all the instructions closely. When complete, print your work in normal view and formula view making sure that the print fits on one page and shows the gridlines and row and column headings.
