In order to pipe the sum value to the next question of the survey, we will need to store the sum value on a custom variable (which is previously not used on the survey, else the data will be overwritten) and then use the syntax of that custom variable on the next question where we want to pipe the value.

To store the value on a custom variable, please open the question setting, click on the drop-down menu of ‘Save Sum Value As’, and select the variable you want to use (screenshot: https://prnt.sc/Lj1RbuBOMVRi). Now let’s assume, we used the custom variable 1 to store the sum value so in that case we will need to use the syntax as ${custom1} on the next question, accordingly for custom 2 it would be ${custom2}, for custom 10 it would be ${custom10} and so on.
