Couple eigenvalue equation and ordinary PDE

I am trying to couple the solution of an eigenvalue equation and the solution of Poissons equation in COMSOL.
In the eigenvalue equation the solution to Poissons equation enters as u2. In Poissons equation the solutions to the eigenvalue equations appear as a sum of the first 3 eigenmodes. How can I set up the PDE interface such that COMSOL knows to call the eigensolutions u_i and u2 when solving the problem?
I have attached my script below.
Edit: I attached a newer version where I perform study1 in two steps: First the eigenvalue equation, then Poissons equation. The problem still persists however, that comsol does not recognize the solutions from each step.
