We have a large collection of mail merge templates containing an "Invalid
Merge Field" (ie field is not in the data source)

Option 1 is to add the missing field to the data source.
-i.e. an empty data item

Option 2 is to remove the missing field by VB

I have found scripts that process folders of documents.
eg http://gregmaxey.mvps.org/Process_Batch_Folder.htm

I'm not sure how to remove a mail merge field (eg "InvalidField").
Changing it is not any use to me.
I can modify the data source to prevent the "Invalid Merge Field" dialog
appearing during processing

We are using Word 2002.
