Hi everyone, Im trying to make the value of "assigned_to" go to a "List" field everytime the "assigned_to" changes, unfortunatly Im not being able to make it work, does anyone know how to do this ?

You can create an onBefore Business Rule and add a condition Assigned To Changes

And in the script you can do

if (current.<list field>)
     current.<list field>= current.<list field>+','+current.assigned_to;
else
     current.<list field> = current.assigned_to;
