To use mail merge to create a batch of gift certificates or coupons with tracking numbers, you need to set up a data source that contains a column listing the tracking numbers. If you plan to add only the tracking numbers to your publications, create a data source for the tracking numbers. If you also plan to use mail merge to insert additional information into your publications, such as customer names or addresses, you can add the column of tracking numbers to a data source that also lists the name and address data that you want to use.
I'm using Column A of a spreadsheet to number some items in Column B. I've been using Excel's automatic series-filling function, where you drag down from the lower right corner of a cell. However, since some of the rows in Column B are empty, and I don't want them numbered, I have to stop numbering and manually "jump" over the blanks in Column A. Is there a way to automatically number down in Column A, while skipping over the blanks and continuing where I left off? I.e. 1 2 3 4 5 ? Thanks much. Try this in A1: =IF(B1<>"",COUNTA($B$1:B1),"...

You may wonder whether typing 1, 2, and 3 would be easier than using the ListNum field. Although doing that may be easier initially, the value of using the ListNum field becomes apparent when you cut and paste. When a paragraph contains multiple numbered items that you move or delete, Word automatically updates the ListNum fields. Using ListNum fields assures you of accurate numbering within a paragraph throughout the document.

Tip  Follow the same steps (above) to create Request for Production or Request for Admissions. The only difference would be in Step 3, you would change the "rog" to "rpf" or "rfa". This will keep unique numbering schemes running in the same document. Therefore, you could have an Interrogatory No.1 as well as Request for Production No.1. Keep in mind that if you cut, copy or paste sequence codes, you'll need to select them and press F9 to update the field codes. They do not update automatically. raffle ticket numbering
