Tks. Some queries gave the exact problem explained in this video, and yes, the second quey is not always the salution, especially for a report or form with a complex recordsouce! So, i then go back and re-Eval the output and go from there... SIMPLIFY!

Great video, Richard! I like to periodically go thru "Beginner" lessons. I'm always learning something I forgot, missed, or a new capability added by the devs!

[@oguve278]

If this were a form, I’m assuming it would be possible to do this using SQL statements (perhaps one statement) in VBA instead of queries ?

[@xavierbatlle1828]

Great tip! I use all the time querys from querys from querys... It' much more easy to debug. 😊

Enjoy watching your vids!

[@mitchellfolbe8729]

Why is the first letter at position=1 instead of position=0 like it is in coding?

[@gregoryjeffries8475]

This reminds me of auto vin numbers.

Thanks 🙏 so much
