Help with Drag&Drop

I need your help! :)

I`ve designed a drag & drop interaction. After both shapes have been correctly assigned, a level with "correct" should be displayed automatically. It should appear automatically after the last assignment. So that no tick has to be pressed to send.

Therefore, I have given both forms a variable. I have set this to correct. Then I created a level that should appear when both variables are set to correct. But unfortunately it does not work.

Does anyone here know what mistake I have made? I have attached my file. Thank you very much!
