What does the "Enter Parameter Value" error in Microsoft Access mean? How to fix an unwanted popup.

In this video I'm going to show you how to fix the dreaded "Enter Parameter Value" error when it pops up on you unexpectedly. Alison from Madrid, Spain (a Gold Member) asks: My database has been working just fine for months. I made a few changes, and now my order form is giving me this popup that says "Enter Parameter Value" and asking for the ExtPrice, which it's supposed to be calculating in a query. I have no idea what's wrong. Help, please! BONUS FOR CHANNEL MEMBERS: Silver Members and up get access to an Extended Cut of this video. I'll show you how to work with the Query Parameters dialog. We'll talk about why Option Explicit is important, and why you should Compile your code. We'll also discuss why it's difficult to catch errors inside command strings.
