Adding 1 to a NUMBER

[sportzguy933]

Hi. I want to be able to add/subtract 1 to a number that is in a dynamic text box, when the user presses the up or down arrows (up to add down to subtract). I know how to control the up and down arrows, my problem is adding 1. I can't seem to mathematically add 1... I can make it so that when the user clicks the up arrow, it adds a 1 to whatever was in it before, so basically, if the contents was 02 before, it would turn into 021... But I want it to go from 02 to 03, or 02 to 01! HOW CAN I DO THIS?!?!
Any help is GREATLY appreciated!!

Thanks,

they all have proceeding zeros?

if the number in the text box is a variable (like textField == 1) you would just put textField++ on your up button and textField-- on your down button. To include a 0 before changes things a bit, you would have to put something like:

"0" + textField++ which would include a 0 before your number which would work up until you hit a 3 digit number cause then it would be som ething like 0100 for 100 so you would need an if statement to remove the 0 if the number is more than 99.. Im sure I've provided too much info so feel free to ask me what the hell im talking about lol

good luck!

Hey. I understand exactly what you're saying, the problem is, it's not working. I'd actually rather not have the "0" in front, so that's not a problem. The probem is that I've done what you suggested, and it doesn't work! The code I have now is:

on (keyPress "<Up>") {
textBox++
}

And it doesn't add one! I just get "NaN", or "Undefined".

textBox="0"+(Number(textBox)+1);

if you don't want the String "0" just keep the second part:
Number(textBox)+1;
