App construction problem after copied a screen

after I copied a screen I can not build the app anymore (see screenshot below)

Also, I have no errors (say no warnings or similar)

Can anyone help me with that?

You have some duplicated event blocks. Click the Show Warnings button and it’ll show you which blocks are causing the problem.

This is the Problem. I have no Warnings…

And i can’t find any duplicated block…
Shall I send you the aia. to see if you can build the app? If so, I’ll send it to you privately.

Happy Birthday @Conor :smiley:

Yeah, you can send it to me and I’ll see if I can figure out the issue.

Thank you!

Thanks! I have sent it to you.
