Assuming that you are using mailmerge to create the labels, the best thing
would be to create a new mailmerge main document based on the 8162 label
that uses the same data source.
If the addresses that you want to use are already in a 8163 document and/or
you no longer have the data source, see the article "Convert Labels into
Mail Merge Data File" on fellow MVP Graham Mayor's website at:

Hope this helps.
Please reply to the newsgroup unless you wish to avail yourself of my
