Read Write Problem

I am using Pic Basic Pro ver 2.5 with a 16f876a chip.

My program has exceeded the Page Boundary, but based on reading some earlier posts this should not be a problem. However, I am unable to write to the chips non-volatile memory. Is it possible this code boundary is affecting my ability to use the "read" and "write" command?

READ and WRITE commands should not be affected by a Page Boundary cross.
