Hey, thanks for your help.
I actually spotted my own mistake, it must be input as a string and not a number. But thanks for your answer anyway.

Another option (instead of str2num or sprintf) is to use string operations.
og_rows = 15360;
og_cols = 1024;
title("Form Removed Data " + og_rows + " x " + og_cols)
