HI, everyone:
I am trying to sum up the prices in the shopping cart which is a repeating group, but sum is not showing as an action I can select even after I converted the price to number and decimal. Any ideas why?
Thank you.
‘Sum’ is a number list operator - it can only be used on, and will only be available for, a list of numbers.
Your current expression is evaluating not to a list of numbers, but rather to a single number - so obviously you can’t sum a single number.
But it’s only a single number right now because there’s only a single item in the cart. More items will be added to the list later…
No, its a single number because you’re only selected a single number (i.e. item #3)
