HUmm what to call it?? filter? Correct code? Linking?

[NewfieSarah]

Does anyone know if this code is correct?? I am linking my Main form Address value to my inspections form constr_location value. However the inspections form is linked throguh my building form.
Main - building - inspection
address3- pin- constr_location
This works fine on another form that I have it is just not working on this one.
framfiltval = "CONSTR_LOCATION = " + "'" + Form_PID.ADDRESS3.Value + "'"
Form.Filter = framfiltval
Form.FilterOn = True
