Is there a function to identify the maximum value entered in a numeric list question?

Sumeshsdn I figured it out! I expect that your specific approach might vary depending on what type of followup question you want to ask, but the principle would be the same:
First, set up your initial constant sum question. In this case, we're asking the respondent how they allocate their attention/fandom to various team sports (Notice that the validation is set to total to 100):
Next, set up your followup question to pipe the highest value answer into the question. (Do this by clicking on the text and choosing "Piped Text" and selecting the text that you would like to appear in the followup question.) In this case I've chosen a text question but I suspect that it would work if you want to pipe it in as an answer choice to a different type of question.
The important thing is to insert a page break between both questions: this will enable the system to recognize the highest-value answer and then insert the right text.
I hope this helps! Thanks for clarifying-we both learned something new today!
