This took a while to figure out but Art Polk came to the rescue.
I had a popup form that when a button was pressed I needed to update the subform of the form which created the popup I was currently in. Basically, I used a popup to edit one of the records in a data grid. My objective was that once the update was processed the grid would refresh displaying the change…
Forms!frmParentFormName.Controls(“frmSubFormNeedingTheRefresh”).Form.Refresh
That’s it
