Customized Piping : Dynamic Constant Sum Questions

The Custom Validation : Piped Data Prior Question allows you to configure the total for a Constant Sum question based on a response from the respondent to a prior question.

For example : If you have a question that asks for the respondents monthly income, and then have the respondent fill out a constant sum question that totals to the respondents monthly income.

Important Notes

There has to be a page-break between the "Source" question and the Constant Sum Question

Validation must be turned on for Dyanmic Constant Sum Total.

The "Source" question should be a Numeric Question Type and MUST BE A REQUIRED OPTION i.e. users must fill in a numeric value. User should NOT enter in symbols like "$" etc. when entering values for the "Source" question
