It’s a difficulty with the ‘try’ it just skips the bit you’re interested in…
If you just put it in a ‘for’ you’ll likely get an error message saying that something didn’t work?
Better still you would adjust the ‘try’ to output an error message, you see it in Konrad’s old code, I just had a look in ‘Get Built In Parameter’ but I’m not sure if he’d object to me just copying it all in!
Hope that helps,
Mark
