I want to be able to compare text value (containing space, slash, colon) with earlier value, not previous. somthing like:
(last(#1) equal to last(#2)) but not equal to last(#3).
My expression is :
But I have the following error in my server log:
Format error or unsupported operator. Exp: [C: F:]
Expression [(C: F: =C: F: )&(C: F: #C: F: )] cannot be evaluated: Format error or unsupported operator. Exp: [C: F:]
How can I do this compare ?
