Thanks Frank,
but that just gives an error if it's not uppercase. I really need to
change the entry to uppercase if someone enters it in lower. I think
it may be impossible without writing a macro to check after each
entry and then overwriting the entry.

Hi
you could use a custom validation. e.g. for cell A1 goto 'Data -
Validation' and enter the formula
=EXACT(A1,UPPER(A1))
