Richard,
I think you're saying how do I force entries in a field to be Upper Case,
even if the user enters the data in Lower Case?
On the AfterUpdate event of a field called (ex.) [MyField1]... and a user
entry of "aBcDeF"
[MyField1] = UCase([MyField1])
will store the entry in Upper case even if the user entered uppercase,
lowercase, or a mix of each ("ABCDEF")
Note: Just using the ">" Format for a field will DISPLAY any entry in
upper case, but does not save the data in the table as uppercase.
