Your code mentions two different popup forms - htm_training_plan_uebungskategorie(popup1) and htm_training_plan_uebungen_kategorie(popup2). If you look at FAQ79 you will see that the same popup form is mentioned twice. Your mistake is that it is calling one popup form, then checking that it has returned from another, which causes a loop.

The logic behind that code is as follows:
1) If, at the start of the POPUP2 form, there is no value for the primary key of the outer entity then it calls a popup to obtain it.
2) If, upon returning from that popup, no value has been chosen then it will return to the previous form with an error message.
3) If a value from the popup has been selected the current POPUP2 form will use it to read the outer entity so it can then retrieve related entries from the inner entity.
