Referencing a field on a subform

See attached.

I have a header form (frmPackHeader) and a subform (frmPackDetail).
(One to many relationship)

On the header there is a button that activates the code below.
In particular note

WHERE (((tblPackDetail.PackDetailID)=[forms]![frmPackDetail]![PackDetailID]));

When I click on the button I am prompted to enter [forms]![frmPackDetail]![PackDetailID].  WHY ?
Surely the [forms]![frmPackDetail]![PackDetailID] field already has a value??  Why do I need to input it?


I hope the above is clear ...?
Private Sub Command7_Click()
DoCmd.OpenQuery "query1"
End Sub

Open in new window

Change your query criteria to:

[forms]![frmPackHeader]![frmPackDetail].[Form].[PackDetailID]

OR   [forms]![frmPackHeader]![PackDetailID]

depending on where you are trying to get the ID from ... Main for or Sub form (this would be Main form - first post is for SubForm)
