Am trying a new type of flow where after a new SharePoint list entry is added (which collates responses from a Form), two separate SharePoint list entries are generated which extrapolates certain fields (so, for example, we have multi-select questions in the form and that spits out a single string with all items selected; the extrapolation I'm looking to achieve looks for whether each potential tickbox item is present in the output and generates an individual binary variable for each (e.g., for a string showing all feedback methods used, I have a variable for whether or not Feedback Method A is listed, then Method B...).
To complicate matters, there are multiple versions of each question so I'm using expressions to determine what to inspect, so there's a lot of 'if' statements, and a few include 'either', 'and' or 'not'. I assume this is what is being referred to with the following error message, emphasis added:
Unable to process template language expressions in action 'Create_item:_Assessment_and_Accessibility_Extrapolation' inputs at line '0' and column '0': 'The template function 'either' is not defined or not valid.'.
Tried looking at similar community posts but not seeing any that are specific to the 'either' function; the ones looking at other functions aren't helping (there's a lot of date/time format which don't appear to relate); and some are providing JSON output which I'm not seeing.
Help please!
