4. HW2 Requirements
3. The Payment function on pages 557 & 558 may be used to calculate the monthly payment:
Pmt(dblMonthlyRate, dblMonths, dblAmount)
4. You must convert the user's textbox input from text to the data type double:
CDbl(ExpressiontoConvert)  'Convert to Double
5. Format the results with the FormatCurrency function found on page 114.

5. HW2 Requirements
6. The following formulas may be used in your solution:
dblMonthlyRate = CDbl(txtRate.Text) /1200
dblMonths = CDbl(txtYears.Text) * 12
dblAmount = CDbl(txtAmount.Text)
lblMonthlyPayment.Text = - Pmt(dblMonthlyRate, dblMonths, dblAmount)
Note: I divided the Monthly rate by "1200" vice "12“ to allow the user to enter a whole number (i.e 7.0 vice .07). You need a minus sign before the Pmt function to make a positive answer.
