Thank you very much for being so patient with me. Now that you've shown me the problem, I've tried reading about it, but I am doing something wrong. I had two unbounded controls. I deleted their ControlSource property and tried to do what what you suggested:
Me.txtTitle_Name = Me.txtText56
(I used to have =[Text56] in the ControlSource)
Me.txtImpact_Name = IIf([Cost_Name]>=[Performance_Name] And [Cost_Name]>=[Schedule_Name],[Cost_Name],IIf([Performance_Name]>=[Schedule_Name],[Performance_Name],[Schedule_Name]))
(this expression used to be in the ControlSource)
Thank you again for the help, I would really like to understand how this works- I have a feeling it will greatly improve my work in Access in the future.
