MS Word Mail Merge, 3 records per page?

Scanned the forums here and elsewhere and nothing seems to fix what (in my mind) should be something very basic.

I have a Mail merge (for invoices) there are 3 Invoices per page. Each invoice is for a different customer. See the attachment.

I Created Mail Merge using Labels, 3 rows 1 column. When I run the mail merge, instead of each label having a new customer, it prints 1 page with the same customer 3 times, the next page has the next customer 3 times, and so on.

How do I simply tell Word to change to the next person after the first label, instead of the the 2nd page???

Help please

Never mind. It is working now using the next record option...

With you label merge, you need to insert a NextRecord before the first mergefield on each of the 2nd & 3rd labels. You'll find the NextRecord option in the 'Rules' dropdown.
