Attached is a trigger to grab values from the On_Call_Schedule object which stores the values I grab. I'm attempting to convert the location__c field to a mulitpick picklist. I've succeeded in the conversion of the actual field but now need converting the trigger to handle the possible multi value String in the List. As you can see, location__c is mapped with the Id of the On_Call_Schedule so that later is can be called to populate the Incident object that triggers it. I feel like it would be easiest to somehow store the multivalue string as a Set then parse it later. I've also considered moving the Maps and Lists under the Trigger.New statement so that I can just grab the Queue name from the Incident and add basically 'AND location__c = d.Owner.Id' to the SOQL for onCallList.

Disclaimer: I didn't originally write this so I may not be able to defend 'Why'. I've renamed variables and added notation for my sanity.
