Tom,

You can't do it that way. However, you can use the * and ?
wildcard characters in a COUNTIF, so try something like

=IF(COUNTIF(B1,"??/???"),TRUE,FALSE)

I'd like to make a worksheet function like this:

=If(B1 Like "##/###", True, False)

Hi Tom,

The Search() function enables you to do this.
It is using a limited number of metacharacters: * and ?

Is it possible to use the Like operator as a
