set default value to value on main form

[tizwaz]

i have a form with 3 sub forms. I want the default value of the contractID on the sub forms to be the contractID on the main form. What is the correct syntax - I can't seem to get it to work

What have you tried?

 

[tizwaz]

=[Forms]![frmContractDetails]![contractID] in the default value property of the subform

Have you considered setting the Link Child and Link Master Fields to ContractID? This will have the same effect.

If you want the change in default value to have an immediate effect, try:

Private Sub ContractID_AfterUpdate()
Me.[i][Subform Control Name][/i].Form.ContractID.DefaultValue = Me.ContractID
End Sub

Otherwise, setting the default value as you show seems to work for me, but not for the current record.
