I have two lists on the site. The one list has a reference number that refers to the other list. I am trying to put together a workflow with a query that gets all items with the related reference from the list but am having some challenges in updating the lookup field. I am getting the right ID's from the list but when i attempt to update the item all I get is "Error updating a list item" With Outcome "Unknown error".
I am pretty certain my problem is how i am building my variable is use to update the Lookup field.
