yes, you can grab the value of the textbox and match it against a

Hey Michael,
I don't think that regular expression is going to work. If you're
using a regular expression constructor method, as opposed to a
literal, you shouldn't use the slashes. Even without the slashes, that
test will always return true as long as the string has one upper or
lower case letter from a to z.
The OP wanted to disallow numbers, so this should do it:
if ( !(/\d/).test("string") ) {
return 'valid';
} else {
return 'not valid';
}
