Portal1 on my Music Table layout has condition of side="A" and Portal2 condition of side="B". The portals contain the name of Artist and Track Name(s).

When the Format=Single, I'd like the Portal1 Artist and Track_Name to appear in lieu of the Album_Title/Artist, per side. Tried If statements but not sure how to address the fields within the Portals.

You could layer the fields and use hide conditions based on format=single 

Or, use a single segment button bar in the portal as a layout calc.

That was my first thought but I am not sure how to address the field itself that's in the portal. The field "sideAB" is conditional on the setting for the format. Portal 1 = sideAB TimeCalc::side AorB = "A" and Portal 2 = sideAB TimeCalc::side AorB = "B" stumps me.
