The sum question option either validates that answers given in a text response grid question add up to a particular value or simply sums them up. You have the option of showing respondents a running total of what they have entered so far and the required sum.

To add a sum:

- Add a text response grid question.
- Click on
**Options**at the bottom of the palette. - Enter the total for the question into the
**Sum**box. Or, if you simply want to add the values together but do not require them to match a certain value, enter “-”. - Optionally, edit or delete the
**Sum Label**. These are the instructions that will display to respondents. The placeholder {y} shows respondents their current total and the placeholder {x} shows respondents the required total.
