I suspect my solution is very simple, but I'm struggling with it. I have a table (tblProjects) containing 3 fields (ProjectID, ProjectName, ProjectSize) which I am viewing on a form. When the user selects the ProjectName via a combo box, I want the corresponding project size to appear in a text box on the form. I've tried using both the Table and a Query as my row source, but I don't get any data in my text box. Sounds very basic! Any thoughts?
