Found value count and word count functions... is there a way to count characters in a field?

What I want to do is give a field a max num of characters but do this as a calculated validation so I can display custom message. (I have some other validation criteria also so I don't want default validation error msgs here)

If(Length(your field)>number;0;1)

Or

Length(yourField) <= number

This will naturally return a 1 when true and zero when false.

Ah! "Length"... knew there had to be a function for it somewhere!

Thanks!
