This is my Custom Function and I want to edit it


The function needs an additional Case condition to check that the field itself is not empty, otherwise it returns a "U" for empty fields.

Very useful. Here's an updated version with more options.

/* Determines the status of a text string as Empty, Upper, Numbers Only, Lower, or Mixed case.
May return "Upper" if no a-Z characters are found.
Used the fact that the Substitute function is case sensitive */

Case (
theText=""; "Empty";
Filter ( theText; "0123456789") <> "" and Filter ( theText; "+-*/_.,()") <> ""; "Numbers Only"; // Phone number or calc
Substitute ( theText ; Upper ( theText ) ; "" ) = "" ; "Upper" ;
Substitute ( theText ; Lower ( theText ) ; "" ) = "" ; "Lower" ;
"Mixed" // for "mixed case"
