I have a lottery program nearly completed, thought i had the last of the problems sorted but it seems i did not!!
The program has a couple of issues.
1: Everytime i click a button it stores what i clicked, for example 10, and also creates a random number. Problem is what's happening is i click my first choice, it compares it to the first random number, i click choice 2, it compares it to random number 2, and so on...naturally this is a problem. I want it to take my 6 inputted numbers, then compare Against ALL the 6 random numbers it generated for me, not on a 1 on 1 basis..
The problem is in the logic in my "for" loop but i just can't seem to get it i've tried all avenues!!
