Continuous Sum Question Type

Continuous Sum questions allow respondents to enter numeric values (often percentages or dollar amounts) for a list of items that are then summed for a total value.

When To Use It

This question type is used to see how a larger value, such as a budget, is allocated across several items.


  1. Click the Question link on the page where you would like to add your Continuous Sum question.
  2. Select Continuous Sum from the Question Type dropdown.
  3. Add the question you wish to ask and your answer options (these are the categories you wish to sum). Use the Default Value column to pre-fill fields in your list, if needed.

  4. Before saving, navigate to the Validation tab to set up validation, such as percent or currency, a max total, and other advanced settings.

Note: Negative values can be used in this question type.

Validation Settings

A number of validation options specific to this question type are available:
Continuous Sum Validation Options

  • Max Total - The max total is the desired sum that your respondents' entries should reach. This field is not required.

    • The answers for this question *must* equal max - When this option is selected respondents will not be allowed to move past your continuous sum question without entering values that sum to the Max Total.
    • Hide Maximum Value - This will hide the Max Total value from respondents.

  • Answer Format - By default, Continuous Sum questions are set up to collect numeric data. This validation can be changed to require either Percent or Currency entries. You can also force a Whole Number here, to ensure that no negative values are entered.
  • Allow values between - You can set a minimum and/or a maximum allowed for each field.
  • Limit answers to - Use this field to determine the number of fields that must be answered within the list.

Layout Options

There are a coupe layout options that can help you customize your continuous sum question.

  • By default, the continuous sum labels are placed on the right side of the textboxes. Un-check the Place labels on the right side of the input setting to move the labels to the left.
  • If you need to allow more space for your continuous sum entries, use the Textbox Width field to do so.

Survey Taking

On a desktop and most laptops, the Continuous Sum question type looks like so.

When optimized for mobile devices the Continuous Sum question type looks very similar.

By default, survey questions show one at a time on mobile devices to prevent the need for scrolling on smaller screens. You can turn off this one-at-a-time interaction if you wish.
