Constant sum is a method that will allow us to setup and group multiple constant sum fields together to ask the respondent to enter a values that will match the total value we've specified.

In the example above we have a question with three constant sum fields linked using the connections of the type settings. The respondent will need to answer each field with a number and the total of all fields must reach 100.

In order to make constant sum work we always need to have a "master" ranking type that will manage the values of the group of constant sum fields.

 

In this case the "master" type is "Quality". "Quality" has subscribed to the other constant sum types value using the connections of the type settings. We have also set the total of the sum to reach from the extended settings of the "Quality" type.

 

The field is not mandatory by default, if you want to make it mandatory you make check the mandatory option in the type settings.

 

We can set following properties to customize our ranking  types :
