Please don’t apologise for inexperience, we’re were all there once !

Just double checked it and the code is fine.

Probably an issue with you either not copying across fully, or a paste error.

Delete the code, copy across again and retry

if it still fails, come back with the bit of code that is on the line it falls at (and the line before please!)

and I’ll look further

You’re welcome !
