I use maths operations in embedded data in survey flow to calculate percentages from data provided in a respondent's survey. That gives me dynamic data for each respondent that I can average across all respondents and report in a dashboard widget (I'll share some widgets with respondents). However, the maths operations return a zero value when a respondent has skipped that question. For example, if I have 20 respondents, but 10 skip the question, my maths operations is returning 0 for those ten when they should be null. This in turn skews the average when I report in a widget.
This must be a very common problem. Maths ops don't permit if statement as far as I can see - what am I missing? I hope someone can help - thanks
