If I use an event. How can I manually trigger an error condition so that
the
user will be forced to re-input the cell with a valid entry?

I have several function that needs to be done as part of validation.
This
requires that I call a custom function. Is there a way that I can
call a
custom function from the data validation? I see many examples that
calls
standard Excel functions but I do not see any custom calls.

Also, which is faster? A validation done using the Data Validation or
an
event trigger? I will be validating between 10000 and 15000 rows.
