Question : MS Access - Move focus from one form to another form with VBA and enable controls

I have a form  titled "F-100-05" .When I click a button on this screen I want to move to another form "F-100-04" and then enable the following fields on this form ( F-100-04), "Pu-VIN", Pu-Year".  
I do not have the correct syntax to do this.
How do I write the VBA code to do this.

Answer : MS Access - Move focus from one form to another form with VBA and enable controls

If form " is open then do..

Forms![F-100-04].setfocus
Forms![F-100-04].[Pu_vin].enabled = true
Forms![F-100-04].[Pu_year].enabled = true
Forms![F-100-04].[Pu_vin].setfocus  ' or wherever you want the focus

If the form is not open you will need an extra first line..
Docmd.Openform "F-100-04"
