Beeping error on Combo Box

[cgemmill1]

I have a form with a subform. I added a combo box to the subform that list out the staff names. When I go to the form view I can activate the drop down but get an annoying beep when I try to click on a staff name. I have a simar form with the staff information and it works. I do not see differecnes between the two.

Your record source is non updateable. Do you have more than one table in the form's record source?
