Validation Problem On TextBox

[Hainesey]

The textbox isn't linked to a field, so I've entered a validation rule in it's properties which is -

Len('txtDescription')<=5

Just to test it...I actually want it to limit to 100 characters but just making sure it works - which it doesn't.

If I entered less than 5, 5 or more than 5 characters the validation text pops up.

Any ideas?
