the break piint occured there. I had to rememeber to remove this statament .
Breakpoint is an excellent idea.

Hi R.Venkataraman,

When we put a code in the standard module it is possible to step by step
running the procedure to find out any bug. However in workbook or
worksheet
even procedure it is not possible to debug in this way. If you click F8
nothing happens. Is there any method
for debugging a thisworkbook/worksheet event procedure.


Go to the procedure in question, click in the first executable line of
code
and hit F9 to insert a breakpoint. Then do something that makes the event
code
fire and the VBE will halt at that line.
