Not garbage but I have no idea what made you think you need all of those variables:
'In ThisDocument or a Standard Module
Sub frmPSAShow()
Dim oFrm As frmPSA
Set oFrm = New frmPSA
oFrm.Show
Unload frmPSA
Set oFrm = Nothing
lbl_Exit:
Exit Sub
End Sub
'In the form module.
Private Sub cmdOk_Click()
Dim strOutput As String
Dim lngIndex As Long
For lngIndex = 1 To 10
If Me.Controls("OptionButton" & lngIndex) Then
strOutput = strOutput & Controls("OptionButton" & lngIndex).Caption & ", "
End If
Next
If Right(strOutput, 2) = ", " Then strOutput = Left(strOutput, Len(strOutput) - 2)
ActiveDocument.FormFields("PSA").Result = strOutput
Hide
lbl_Exit:
Exit Sub
End Sub
