Hi everyone, 

I hope you are well. 

I am currently trying to build a report that shows how much time each learner has spent learning to date? Is there a way of doing this. I had thought I could use Learner First Name, Learner Last Name and then the maximum duration value from a course. But I can't seem to find the correct fields to put into my report. 

Has anyone done this before? Which fields did you use?

Any help would be welcome!!
