Hi Mark,
isn't it? maybe I'm misunderstanding what you have in mind?
I tried this in a tip;
format(Pre:Time,@t1) & ' >>' & format(Pre:Time+Pre:Duration,@t1) & '<br/><strong>' & clip(Pre:Title) & '</strong><br/>by ' & clip(Use:CombinedName)
and it came out as I would expect.
So maybe more context is in order?
cheers
Bruce
