Trigger on Opportunity to update User object
I need to make a trigger on the opportunity object that Adds +1 to a custom filed on the user object every time an opportunity that the user owns has the "Date qualified" field changed from null to having a date.
What I am trying to do is get a count on the user object of how many opps are qualified MTD. Then I can run a report that will show how many reps that have zero opps along with the reps that have opps.
I tired making a workflow but the field update can't cross to the user object. And I am not sure were to start on this code. Any help would be great.
