Displaying Blanks when Summing to Zero

When you are working with tables in Word, you can use a field to sum the values in a range of cells or in an entire column. Normally, if the sum of the range is zero, the field displays a 0—this seems reasonable. You may, however, want the field to display a blank when the sum is zero, instead of the actual number 0.

To do this, simply modify your sum formula as follows:

{ =SUM(ABOVE) \# #;-#; }

Notice the addition of several parameters after the SUM formula. The first (\#) is known as a numeric picture field switch. It tells Word that the following codes represent a picture of how you want numeric information displayed. The second switch (just before the first semicolon) indicates how you want positive numbers to display. The second (just before the second semicolon) indicates how you want negative numbers to display. The final one (in this case blank, just after the second semicolon) indicates how you want zero values to display. Since this is blank, zero values are displayed as blanks.

You can apply the same logic if you want to display dollar values. Simply change the formatting codes used in the field to match how you want the data displayed:

{ =SUM(ABOVE) \# $#,##0.00;($#,##0.00); }

Here positive numbers are displayed with a dollar sign, commas (if necessary) and two decimal places. Negative values are displayed the same, except there are parentheses around the number. Again, zero values are left blank.
