Chart links with mail merge
 

I have a word document containing mail merge fields using data from an Excel
spreadsheet - this works fine. I also have some charts in the spreadsheet
which I'd like to link to the Word document. I've used the Paste-Link
command and these update automatically as required.

However, when I close the Word Document and re-open it, the chart links are
lost and the charts now behave as though they are pictures. How can I stop
this happening? Do I need to insert the charts in a similar way to the other
mail merge fields?

Any help will be gratefully received!!
