This code fails:

```auto
selectedRow = event.source.parent.parent.getComponent('Table_Trailers').selectedRow
if selectedRow = -1:
	system.gui.messageBox("Must select Row to update")
else:
	param1 = event.source.parent.parent.getComponent('Table_Trailers').data.getValueAt(selectedRow,"Record_ID")
	system.nav.openWindow('YARD/Yard_Update_PopUp', {'SelectedRow' : param1})
	system.nav.centerWindow('YARD/Yard_Update_PopUp')
```

Right, you need to have a double equals when checking for equality:`selectedRow = event.source.parent.parent.getComponent('Table_Trailers').selectedRow
if selectedRow == -1:
   system.gui.messageBox("Must select Row to update")
else:
   param1 = event.source.parent.parent.getComponent('Table_Trailers').data.getValueAt(selectedRow,"Record_ID")
   system.nav.openWindow('YARD/Yard_Update_PopUp', {'SelectedRow' : param1})
   system.nav.centerWindow('YARD/Yard_Update_PopUp')`

Sweet… I think I love you. Funny how something so small can be so frustrating.
