Error message when using before update event procedure

[Scott]

When I put anything in before update event procedure of an input form, below
error message came up.

Error message

Microsoft Office Access

The expression Before Update you entered as the event property setting
produced the following error: A problem occurred while Microsoft Office
Access was communicating with OLE server or ActiveX control.

*The expression may not result in the name of a macro, the name of a
user-defined function, or [Even Procedure]
*There may have been an error evaluating the function, event, or macro.

It happened on some pcs but not all. Can someone shed any light to me for
the possible causes and fixes.

Thanks,

Scott

Could be several things, Scott, but this sequence should address most of
them:

1. Uncheck the boxes under:
Tools | Options | General | Name AutoCorrect

2. Compact the database to get rid of this junk:
Tools | Database Utilities | Compact/Repair

3. Close Access. Make a backup copy of the file. Decompile the database by
entering something like this at the command prompt while Access is not
running. It is all one line, and include the quotes:
"c:\Program Files\Microsoft office\office\msaccess.exe" /decompile
"c:\MyPath\MyDatabase.mdb"

4. Open Access (holding down the Shift key if you have any startup code),
and compact again.

5. Open a code window.
Choose References from the Tools menu.
Uncheck any references you do not need.
For a list of the ones you typically need in your version of Access, see:

6. Still in the code window, choose Compile from the Debug menu.
Fix any errors, and repeat until it compiles okay.

At this point, you should have a database where the name-autocorrect errors
are gone, the indexes are repaired, inconsistencies between the text- and
compiled-versions of the code are fixed, reference ambiguities are resolved,
and the code syntax is compilable.

If it is still a problem, the next step would be to get Access to rebuild
the database for you. Follow the steps for the first symptom in this
