i created an application with macro excel. one problem occured is when i want to delete one or more row, it appeared a message "illegal operation".

EXCEL caused an invalid page fault in module EXCEL.EXE at 0157:3022dcb7

when i put a breakpoint 1 line before the error line and i do the delete manually, the error still occured.

but when i put a breakpoint more than 3 line before the error line and i do the program manually, the error DID NOT OCCUR.

Please help me, i don't know what's wrong.
Thanks..

Anna
