Harlowe: Referencing a datamap with variables
I'm learning to work with datamaps in Harlowe, and I'm trying to use variables to call up a specific datamap, like this:
Where $temp shares the name with the datamap I want to pull up, and $action is the same as a name in the datamap.
I know that $action fires correctly, because I can put in the exact name of the datamap ("$city") and everything works.
I know that $temp has the right value ("city"), because in my game, ?city becomes clickable when I use the exact name of the datamap.
However, the code above doesn't work, returning nothing, or (if I put in $city instead of the "$" + $temp):
As a further limitation, I can't rename the temp value to $city, because I also need to call upon ?city.
Any help?
(if: "$" + $temp contains $action)[ (click: "?" + $temp)[ (replace: ?reaction)[(print: "$" + $temp's $action)] ] ]

You can only access position strings/numbers ('4th', 'last', '2ndlast', (2), etc.) and 'length' of the string "city", not the string "go".►
