Type mismatch error

[zepol44]

I need some help from someone. I cannot figure out how to clear up a "type mismatch in expression" error in a form that I have created. The data is intact in a linked table to the form but I can't get past the error to fix it. It pops up when I try to open the form. Please help if you can.
-Thanks,

Right click on the form and choose Design to open it in design view.
