I have found that if I give a variable or string a value within a function, it does not have any value (variable is 0, string is empty (ie blank))

I tried converting the function to a sub-routine, and it worked (ie variables were the same outside subroutine)

So, my question is, how do I create a function where the variables exist outside, or am I stuck with sub-routines?

If you define the variable as GLOBAL at top of your code, the variable can be used inside and outside of functions: e.g.

Thanks. How do I do global for an array? Also, does it have to be at the beginning?

I think I remember reading somewhere that dim makes the array global automatically, so long as the array is made from outside the function. I could however be utterly wrong.

Dims that are executed outside of a function are automatically global, but I label mine as global anyway.

the fact that variables are erased out side of functions is because of encapsilation. Basically, it is a feature, not a bug. Looks like everyone else showed the workarounds so good luck!
