Unable To Refresh / Requery Subform Using VBA?

There are 2 levels of forms, the main parent form is called INSPECTION. Then there are two subforms: TESTRESULTS and addTESTRESULTS.

the form TESTRESULTS is linked to the TESTRESULTS query "QTESTRESULTS2". This query looks at two hidden fields on INSPECTION called FILE and REPORT NO. The query finds all fields inside of TESTRESULTS that match the two criteria. This works fine. The form TESTRESULTS is linked to the QTESTRESULTS2 query as direct data source link. This works fine.

a temporary table has been setup to append test results to TESTRESULT table. This works fine. What doesn't work fine is updating the subform TESTRESULTS when needed. I want it so that the welder enters his information, clicks save, the info gets appended to TESTRESULTS table and instantly updates on the form for them to verify.

[inside subroutine for saving a record] all efforts at accessing this form have failed. I've tried !form!subform!requery, it has failed, I've tried making dummy fields inside the form and accessing them and that has failed, I've tried .setfocus on the form and that has failed, each time the compiler tells me 'unknown field', when in fact I'm trying to hit the form itself.

Its worth mentioning that I've set events [on this form for any kind of update event including mouse click] to Me.requery for this form when you click on it, it updates, but I need to automate this somehow, and the form just seems untouchable via VBA.
