I'm not the best with forms, but I can get this to work. Maybe someone knows a better way, but I know this will work.
Change your input forms to labels and then change your VBA code to start with this:
Me!UnitTotalReq.Caption =
Me!UnitTotalCore.Caption =
Me!UnitTotalCont.Caption =
Me!UnitTotal.Caption =
You need to identify the form (Me!) the control (UnitTotal) and the element of that control. I don't know which element of an input box you need to use, but I do know the Caption element of a label is what you need to reference to get it to show what you want.
