error in word VBA to automate creation of mailing labels

[dgr7]

hello,
I'm trying to automate the creation of mailing labels where the source data in an .xls worksheet.
I have the below VBA code that I created first with the macro recorder in word then edited some to put in the Directory and Filename code that I've used successfully in some Excel VBA and VB 6.0 code.
Now I'm having trouble getting the code to work. I run it and I get the error:

Run-time error '509':

This command is not available
and the code execution stops on the line:

WordBasic.MailMergePropagateLabel

Can anyone help me get past this error so the code will run successfully.

thanks in advance,
david
