Compare fields in set analysis

[#1]

Hello All,

I have 2 fields in my table : Project Completion Date and Project due date. Now I need sum of all rows for which the Project completion date > project due date. I tried using the following set analysis but it didnt work.

=Sum({1<[PPO Indicator] = {Close},[Project Status] = {Completed},[Project Completion Date]={">=$(=[Project Due Date])"} >}[Value])

The user does not select any values in these fields.

Thanks

Arun
