As an aside to the other helpers on the forum: Not sure why they'd ban View.Update() though.
The only reason I can think of is to prevent students taking advantage of lazy teachers by doing whatdotcolor checks on the back buffer so it isn't obvious they cheated.
As for OP:
I have tried what I know: loops, elsif, and, if statement
This is like saying "I tried using a hammer" when someone asks what you did to try to build a bookshelf. It's far better to tell us how you used it. "I tried using a hammer to break this board into smaller pieces to use for shelves, but the edges are all messed up and none of them are the right length" is a far better way to answer the question, don't you think? Now we know exactly where our misguided carpenter went wrong!
