Hello,
I have the procedure below in my program which adds a
button with click event code to a specified sheet. This
code works perfectly when I call it once for a sheet or
back-to-back for different sheets. However, if I call it
twice for the same sheet (try to put two buttons with code
on the same sheet), it fails with this error:

EXCEL.EXE Application Error
The instruction at "0x..." referenced memory at "0x...".
The memory could not be "read".

I believe the problem is that the code module in the VBE
stays active (or something to that effect) and the second
button's event code cannot be written there. I have no
idea how to "close" or "deactivate" this so I can write to
the same code module. Can anyone please help me?? If I
take out the code that -er- writes the code, it works fine
even with two buttons on the same page. Any help would be
GREATLY appreciated. This is driving me nuts!

TIA,
Joe (please reply to group)
