So you can’t help me with my problem?

That’s my whole Code, how should I show more?

The one variable (showingPopover) shows a popover. The other variable (selectedPlaceName) sets the value for the contents of the popover. The placeholder for selectedPlaceName is ERROR (if it doesn‘t work, this text will be displayed). So I would now have to set selectedPlaceName before showingPopover (so that it works correctly). What am I doing wrong?
