0 to 60 counter

axial28rr · 2011-05-04 15:25

hey guys

i need to make a 60 second countdown timer with 2 push buttons 1 push button need to set a number in the TENS coulum and sets that number value .

the second pushbutton needs to set a number in the ONES colum then sets that number value

then when both push buttons are pushed it counts down to "0"

this is what i have so far

what am having prblems with is that when i push a button its shows all 9 numbers (0 -9)insted of 1 number

ex i push the push button 6 times i shoud see 0 to 5 on the debug and its sets that number

thanks

As presented , your code won't even compile - the variable "counter" is undefined.
And there are other logical and syntax errors.
You need to compile it first before troubleshooting these errors.

Is this a direct copy from the text you are quoting ?
Can you copy and post the code from the text you are using?

Even if it would compile, it wouldn't run for long. You've got a recursive GOSUB main call and no RETURN anywhere.
