Thanks - just thinking back to when I used to write Basic years ago - there was an "On Error" function you could use.
So there's nothing like that in Brightscript?
Just out of interest.... scouring the net I found some ROKU PDF that refers to Brightsign BrightScript....
and it has this in....which doesn't work .... but just adds to the confusion I guess .... an Older version of Brightscript perhaps???
