Measure If Statement based on Text Column

[Anonymous]

I would like to create a Measure that I can use an If statement based on a column that is Text-based. Essentially I want something that can tell me based on what the Current Phase is, if something is overdue. 

For Example for Project ID #11, since the current phase is DP-C, I would want DP-A and DP-B to show blank in the overdue column, but would want DP-C to show overdue because that Actual Date is < today. However, I can't even get my "Current Phase" column (which is in another table [PP-Project Status]) to show up in my list of columns I can pull into an if statement. Do I have my relationships set up incorrectly?

Create  Current Phase in the  Proejct ID table  using   CurrentPhase = RELATED(PP-Project Status. [CurrentPhase]) and  the you can pull in to  your  if statment .
