Choose 2 answers

Question56: A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the Opportunity's stage is changed, a workflow rule is fired to increase the value of a field by one. The developer wrote an after trigger to create a child record when the field changes from 4 to 5.
A user changes the stage of an Opportunity and manually sets the count field to 4. The count field updates to 5, but the child record is not created.
