Richard, I am working on SQL Seminar 2, lesson 4. At 4:52 in the video you format the markup box as percentage. I do this, but it does not show as such. I saved and closed the form, but -- unlike when you closed and reopened-- it did not change to a percentage. I gave up and decided to continue, but at 12:34 you can change the Markup value manually. I try and Access gives me a message: The value you entered isn't valid for this field. Eg, you may have entered a text in a numberic field or a number that is larger than the FieldSize permits."  I tried typing 0.06, 6, and 6% but none were accepatable.  I am working in Access 2007.  I can choose which category I want from the CategoryCombo and it works, but it shows the percentage as 0.05 or 0.75 in the markup box. It shows it as a percentage in the CategoryCombo. My UpdatePricing button works fine, but again, Bonnie
