I'm not sure what message appears when the cell is *selected*. Are you
referring to the error message that is triggered by an invalid entry? If so,
AFAIK, there is no way to modify it.

Can anyone please offer any advice? ..... I am using data validation on a
worksheet and would like to resize the message box that appears when the
cell is selected. Can this be done in Excel either using an option or by
using some VBA?
Many thanks,
DT.
