Here's a snippet I've been working on to create a map qaulifier table out of one of the tps qaulifier tables in 6E. I already have another basic qualifier inplace, but I'd much rather have a table. Problem is the engine won't stay running long enough for me to diagnose what's killing things. Ideas?
