I am using nintex 2013 and I want to loop through a collection. At first I have the collection action. I added a field to the collection of the current item the workflow is running on (type: person or group). In my example there are two persons in the field. The For each action should send a notification to each person (and when this is working do some more stuff). I get the error:
Coercion Failed: Unable to transform the input lookup datat into the requested type.
What should I do? Is this possible (people collection and looping through it..)
