Convert recalc VBA Expression to Macro

[MikeNificent]

Hi there, I have a db that I would like to get web ready one difficulty I'm having is converting the After Update VBA to macro as web db's don't use VBA.

The VBA expression recalc is what I can't figure out, below is the VBA I want to convert:

Private Sub cboRoom_AfterUpdate()
Me.Recalc
Me.Requery
End Sub

The above is probably a very simple one sorry I just can't figure it out.
