Printing To Labels For Years

I created a wedding list with a bunch of fields for each household: first name person 1, second name person 1, first name person 2, second name person 2, street #, street address, apartment, city, state and zip. Then I realized that I probably needed to combine fields for each line of the address so I created 3 combined fields: 'combined 1 ' that looks like this "joe smith & patsy cline," a 'combined 2,' that looks like "14 jones street, #3," and a 'combined 3,' that looks like "New York, NY 10037."

I haven't printed to labels for years and when I did some quick research via the help function on excel it said to print labels via word...which worked fine until i got to this section: " In the Mail Merge Recipients dialog box, click any column labels in your data that correspond to the Word identifiers on the left. This step makes inserting your data in the form documents easier. For more information about matching fields, see Word Help. "

I have no idea what this means, but here's what I need to figure out: " how do I print labels using just 3 of 8 existing columns in my spreadsheet, i.e I just want to use combined 1, combined 2 and combined 3 for the 3 lines of the address. My first instinct was just to cut the contents of the combined fields into a new spreadsheet and just do it taht way, but I created the combined fields using a formula which relates to the other fields........
