I must have uploaded an incorrect version of the template way back in September. I unexpectedly had to set aside the work until now.

Thanks for the tip on rich-text CCs -- I'd actually run into issues with that and subsequently went with plain-text.

Today I was messing around with dropdowns again, and I've got a work-around, though it's not exactly what I was looking to do: I'm using dropdown CCs bound to custom parts, which works.
