ok, thx for the fast help. when a use scheduleActions, the error is gone. But when to use schedule or execute? In the manual it says a can use the two...

The difference between these two methods is that executeActions() will execute the actions
synchronously, resuming script execution only when the actions are completed. The schedule-
Actions() method however, will execute the actions in the background, and script execution
resumes immediately after invoking the scheduleActions() method.

But stile one gifs a error. But a don't git way

thx
