Nah, you're fine with 179. Heck, you're probably OK with a couple THOUSAND items in the HelperT. You start getting up to 10,000 items and noticing a slowdown, then worry about it. Only over a really slow network or online with a crappy connection would you have a problem with less than 1000 items.

It's all relative to the speed of your computer and your network connection. If you notice someone getting slow, then you can address it then. Either upgrade their network connection or optimize the database. In fact, when I show how to move this puppy up to SQL Server, it won't be a problem because the server will only send the 8 records in the current combo box across the wire. Right now Access has to process ALL of the records (over the wire) and show you the 8 you need. A database server solves that issue.

That's fantastic! I'm just planning ahead and don't want to paint myself in to a corner later on.

Roll on ABCD Core 6!!

You should be fine. If it becomes an issue, let me know. Remember, the HelperT is supposed to be lightweight access to small lists. If you've got a single list that's got hundreds of items, you may want to consider breaking that specific list off into its own table.
