I guess this is pretty fundamental but I cant get it right! I want to search for a member by post code so I need to have validation for my table field post code so that when my parameter query accepts the post code input records will be returned covering all input types e.g. Users can put in CF72 (space)9AD or CF729AD and still get the same records or alternately how do I make users enter Post Codes with the correct UK spacing i.e 4 characters a space then the remaining characters?
