VBA in Word

Hello,
I am having some mailmerge trouble with Access and Word. I have a Form in Access with a button that triggers Word to open a document. That Word document has the following VBA in it to execute the mailmerge upon opening:

Private Sub Document_Open()
Me.MailMerge.OpenDataSource "\\calumet\apps\asset_tracking_system\Current Employee.odc"
Me.MailMerge.ViewMailMergeFieldCodes = False
Me.MailMerge.Destination = wdSendToNewDocument
Me.MailMerge.Execute
Me.Close
End Sub

The Access database is password-protected with "dimension4". When I click the button on the Access form, Word gives me the "Data Link Properties" box. I enter the password and Word creates a new "merged" document with this in it:

Record 1 contained too few data fields.
Record 2 contained too few data fields.

I have removed the password from the database, and the merge works properly, but I need the password for security.
Can anyone help me with the code that needs to be added to make this work?

Thanks a million!
