Then go to each slide and type in your questions and answers for each category. Slides start with # 2 in the top left hand corner and move down to the end of the category then go to the top of the next category to the right. (2-6 then 7-11 etc.) When you run the power point and you click on the dollar amount the question will show up. Click the space bar to see the answer. Click MAIN to return to the category page. The dollar amount will change color to indicate the question has already been used. To reset the game, close the power point and reopen it. If you type .pps at the end it will open in a slideshow. If you type .ppt it will open to edit. Problems contact wpearson@sand.net Have Fun!
