Validation Rule - Letters only

[Rupa]

Hey all

I know this might be really simple for some of the geniuses on this forum. How can I set a validation rule to allow the user to enter letters (A-Z) only please.

Any help will be highly appreciated.

Many thanks,

Rupa

Got it.

For anyone who may want to know. It's: "IsNull" Or Not Like "*[!a-z OR "" ""]*"

Thank you anyway,

Rupa
