Suzanne has an Excel worksheet containing addresses. The ZIP Codes are formatted via the special Excel formatting that maintains leading zeroes. However, when she uses mail merge in Word, the leading zeroes are dropped.
There are several ways you can approach this problem. You could, for instance, go into Excel and create a new column that contains text versions of the numeric ZIP Codes. Here's a handy Excel formula to use to accomplish this:
=RIGHT("00000" & A1, 5)
If you put this formula in a column that has been formatted as text (and the ZIP Code is in cell A1), you end up with text that contains the leading zeroes. You can then use this new column in your merge in Word.
If you don't want to edit the original Excel data, then you should stick with making your changes in the Word merge document. Take a look at the document; it contains merge fields that indicate where the merged data will be placed. These fields also indicate how the merged data should be treated. If you select the merge field for the ZIP Code, you can expand it by pressing Shift+F9. You should see the underlying code that makes up the field. You can then modify the field code so it looks similar to this:
{ MERGEFIELD "Zip" \# 00000-0000 }
The name within the quote marks ("Zip") may well be different; it represents the name of the column in the Excel worksheet that needs to be merged. The important part is to add the formatting switch (\#) followed by the pattern to be used for formatting the merged data. When you are done making the change to the field, you can press Shift+F9 again to collapse the field, and then do your merge.
