Hello again,
Thanks for the replies, browsing the code now, although tiz making me headscratch somewhat. Thank goodness it's been well commented. I still can't work out how to make a report have assessment manager data in it - I'm such a SIMS noob.
Have spoken to the SIMS Manager and she's not been amazingly helpful. Politics is involved as currently there are two traffic lighting systems in school - hers and mine. Mine is in excel, hers is in SIMS. Hers can't do everything mine can do, but in some ways I prefer hers. I think I'll try pushing her to get hers perfect so that SMT can let me drop mine.
I've passed on the traffic lighting that matt40k gave me - lets hope she gets keen.
In the meantime people, thanks for all your ideas, it's given me some thoughts, but in the end the SIMS manager is right, we shouldn't be having two systems in one school.
Thanks All!
