Hi bagginsbill,

Thanks for replying. As I said a couple of posts later, I realised that I was in the wrong thread seeing as this is a VSS thread, not a Matmatic thread.

Anyway, my problem was with the RattleSnake and SnakeSkin scripts (I had success with the Jessi script). Yes, I lifted them off the page, but there was no attached script for these. After I had fixed the "indented block" issue, I compiled them without error but there was no output - and that was my problem.

thanks and regards,
Andrew
