Hello and thank you for your time,
I am trying to compare an old user entered value with a new user entered value from the same field (so logically they are calling the same function), but I cannot use global variables. How do I solve this problem, because local variables get initialized each time the function is called and then deleted when the function ends? I am sure this is a fairly common problem that has at least one very common solution. I only need the easiest solution to understand...Nothing fancy. Please help me!
