Hi All,

Does anyone know how to go about creating a presentation variable for a column then using that presentation variable to compare it against another column in Conditional Format via column properties?

I'm working in Subject Area Payables Invoices - Transactions Real Time and I'd like to make the Invoice Amount column a presentation variable and use it to do a comparison on Invoice Line Amount via Conditional Format.

The end goal is to get the condition to say if these two columns are equal then make the background green.
