Automatic printing invoices from ebay, mail merge help!

I'am making a word template for my ebay invoices to automate the invoice printing proces. I use the "mail merge" functionality within Word to get the adresses and sold items for my invoices from the CVS download. Everyting is working fine, except when I have orders with more than 1 sold item

How do I get the multiple items on multiple line in my invoice with "mail merge"?

Help is !
