=myFunction

is a user defined name

=myFunction()

Is that your problem?

All,
I am trying to use a user defined function in the validation for a cell
range. The validation type is custom, and I have a function which is
defined
as Boolean.

I get an error message saying that the referenced named range is invalid.
I
am not using a named range!

Should user defined functions work in validation?

Thanks,
Alex J
