I want to set the allowadditions property of [frmSubForm] to FALSE if a value of a combo [mycombo] in the parent form [frmMain] is "Ordered"

If the user changes this combo (to "Not Ordered") then the allowadditions property gets re set to TRUE.

If the user changes the combo (back to "Ordered") then the allowadditions property gets re set to FALSE.

Use VBA in myCombo's After update event:

Private Sub MyCombo_AfterUpdate()
       If me.MyCombo = "Ordered" THEN Me.frmSubform.form.AllowAdditions = False
       If me.MyCombo = "Not Ordered" THEN Me.frmSubform.form.AllowAdditions = True
End sub

You also need to place this in the form's current event so that the subform will have the property set correctly  as the user scrolls through records.

Thanks, you got me there.

Just had to tweak:

Private Sub MyCombo_AfterUpdate()
       If me.MyCombo.Value = "Ordered" THEN Me.frmSubform.form.AllowAdditions = False
       If me.MyCombo.Value = "Not Ordered" THEN Me.frmSubform.form.AllowAdditions = True
End sub

Glad to help out :-)
I'm suprised you needed the ".Value".  I use the exact syntax I posted routinely.  I use access 2003 where ".value" is the default property.  Your question tags state Access 2000.  I wonder if that accounts for the difference?

I am using 2000... and I tried without .value so I guess 2003 may be different.
