Sorry I forgot to add the code that I had to give an example of what I was talking about.  I’ll put it below, sorry that it’s so long.  A couple of people have basically answered my question though.  I take it was I was talking about was a loop, which I haven’t learned in school yet but, it seems semi self-explanatory.   As you can see I added a loop in there about half way down the code (i put it in bold) and it seemed to do what I want.  Now I’m going to try and do what Rhodri suggested, a range function?  I’m not sure exactly what that’ll do but I think it’ll clean up my code more and make things easier to call?
