I have 2 fields. LastName and Mailto. I want the Mailto field to automatically show "Mr & Mrs" [LastName]. This much I've done but I want the LastName part of the Mailto field to be editable. (As [LastName] part of the Mr & Mrs may be different from the LastName). Of course when I try to edit the LastName part of the Mailto field I can't cause it's bound to the expression.<br><br>Any ideas? Thanks
