Script returns value on test, but not in popup

Hi

 

I created a script to convert UTM32N coordinates to WGS84 Coordinates and put them in a Google Street View parameter to get a dynamic link to Google Street View for every property.

 

The script runs just fine and even returns a nice string that seems very correct when i'm testing the script. Once I save the script and deploy to use in a popup the script doesn't return anything. Is there something I'm doing wrong?
