John, watch this if you need more clarification: Relational Combo

Thank you Richard.  I'll check it out for sure.  Sami, I apologize...I thought because I posted this comment right from the Access Expert 1 page (Lesson 04)...I assumed it would've been self-explanatory.  Next time, I'll be sure to be specific.  Richard's instruction and content have been quite amazing and helpful.

Great video Richard.  I'm not fully confident just yet on how I could implement a relational combo box to my database, but I'm enjoying learning your content.  Thank you.

Think of it like this: If you are working with Excel and you have two different spreadsheets. One spreadsheet has your customers on it, and your second spreadsheet has a list of all of the orders that have been placed. Now instead of typing in all the details for the customer every time they place an order, you just pick their name from a combo box. It's related to the first sheet. It's the same thing in Access. Just with tables, and Access can actually keep track of those relationships.

You seriously make things so easy to understand.
