I've been messing around with the math operations in Qualtrics and have repeatedly been treated with {Invalid Expression}. After some testing I believe it's from the piped text within the expression. For instance, I set up this very simple survey:
I've tested the survey by using the 'Preview' button and have input numbers like 1 or 2 or 3 into text box for Q1. I've also tried changing the validation to make sure whatever entered is a number. However, the expression in Q2 always returns {Invalid Expression}. Is there something wrong with my syntax?
