Hello all,

I am using the ISREF in a cell validation it insure users are entering
valid
range addresses. However, the ISREF is allowing invalid values. See
example
below:

=ISREF(A:WW) = True

If you type this into a cell, Excel changes the "A:WW" to "A:DE".

Since I am using this in a cell validation, the actual cell value does not
change and the validation allows the incorrect data entry.

Does anyone know of solution/replacement formula I can use in my cell
validation.

Thanks for any help you can give me.
