I'm trying to filter by input from an access table. I want to filter only correct postal code formats which is "letter number letter space number letter number". I tried "?#? #?#", but the question mark allows numbers as well for some reason so 11L 1L1 passes the filter which it shouldn't. Also tried "[a-z]#[a-z] #[a-z]#" but it gives error "operator without operand"
Any help is appreciated.
