Hey,
I have to write a program for school which calculates the fibonacci sequence with two inputted integers, but I have to use an array and procedures in order to do it.

I think my problem is probably that I don't understand arrays properly as we've recently done them, but I can't find what's wrong with my code. It runs and the inputs/close programs work okay but it doesn't do the sequences - it just comes up with a large number every time that's like 4 hundred thousand something.

Does anybody have any idea what I could be doing wrong? Here is my code:
