Hello @Paul_HIllen

There are two errors on this page.

1. In “On Page Enter” logic, you trying to get the first occurrence of text with a value which not exists every time. It throws an error trying get first occurrence of text with value which not exist
   
   
2. In “buildingNameBttn” in the list rsBuildingConfigData which does not exist every time you try to get first element. Error same to first. You trying to do something with a value which is not exist
   Also to get the first list element you should use:
