Oh my god I got it. FINALLY.
I thought it out, it was as simple as me having my parent and child fields backwards.
Private Sub Command77_Click()
DoCmd.OpenForm "sfrm_farm_detail", , , "DetailFarmerID = " & Me!FarmerID
End Sub
Finally. Thank you very much for the patience and help literally all afternoon aytee111, I appreciate it a lot. You are what makes this such a great forum website
