Countdown - Performing Addition / Multiplication On Entered Number
Sep 20, 2009I have made an countdown app that is working in a normal way (added picture of it). Now when I select a number in the numeric box and click start, it starts to count down from that many minutes, but what I want is the number I put in the box *3. So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).
