Get Map Value

With this action you can retrieve the value associated with a given key in a map data structure. You supply the variable that holds the map index (as returned by the action Create Map) and then give a "key" (which is the identifier within the map for a value), and also supply a target variable to hold the returned value (which can be flagged as a temporary local variable).

NOTE If you give a key that does not exist in the map then the action will return undefined. You can check for this this using the If Undefined action.
