Stuck in While Loop

VladTeppi (30)
Hello, so for some reason, I can't get out of this while loop. The code takes a Char letter between A-I (depending on the gridSize, depends on the length the grid.) So if the grid is only 2, then you would only get the first 2 letters A, B. The max size is 9, so the last letter should be I.

The while loop makes sure the user does not go outside of the boundary of the Letter's given. When running the code, it can get into the while loop but can never get out for some reason. I've tried outputting the checkBoundX1 and checkBoundX2 to see if it is cause those numbers do not change, but they do change to the correct numbers and I just can't figure out why this is not working :(.

I apologize for the length of the code. Any and all help will be great. Thank you so much!
