Sorry, but I don't understand. How many ways can you attach a template? I thought there was only one:

1. On the Word menu bar, select Developer.
2. Click the Document Template icon.
3. Click Attach next to the Document template field.
4. Select the relevant template.
5. Select the Automatically update document styles checkbox.
6. Click OK.
7. Repeat steps 1 to 4.
8. Clear the Automatically update document styles checkbox.
9. Click OK.

After all this, the relevant Word styles are accessible - but not the quick parts.
