Amazing Amazing Amazing.

Alkhadher Albarkani it sounds like you are just getting your project to assemble and link and you are down to the last error. Overlap such as you describe is likely that you have put data variables with hard coded addresses at the 0x20-0x2F address range and have then also placed bit variables with hard coded addresses in the same area.

Do note that even though your project time is short you are not yet nearly finished if you have just got things to assemble and link. You have the whole debugging phase to go through too. Few programs written and compiled will work right off when placed into the microcontroller program memory.
