Mail Merge Multiple Records on 1 page

I need help with combining several records from an excel spreadsheet into one mail merge document. Specifically, I have multiple records for one customer and wish to display some of the fileds on the document. My worksheet has enough space for 8 acct #'s and corresponding data but cannot write the code so that Word will pull in all the data for each customer. I have attached my doc and data file which is setup fine for merge but cannot code for sequential data to be pulled with a unigue key field. Example: ABC Co. has 4 records, I need to display all four account#.'s and respective data for that record in respective rows.Any help would be greatly appreciated.
