Nested loops, functions...

Hi, it's me again. Sorry if I'm being a pest. u_u



I'm trying to figure out how to make this: a for loop, containing a
function, containing a for loop that uses variables from the parent
loop [tick - can do up to here]. Then, I want to call the function
using a variable that's already used in the function, but with new
values.



I don't think I really understand what I'm trying to do with functions
and variables. Should I try using the func_ functions to do this? Have
I overlooked something really obvious? TIA :)
