error# 5852- object not available - running word mailmerge

[Brian76239]

Trying to automate a mailmerge to run from Access.
Main document opens, but I get the error code when I execute the line:

With .ActiveDocument.MailMerge
.Destination = wdSendToNewDocument
.DataSource = "C:\Transparent\Contract_Print_Temp.odc"
.Execute
End With
