Report value of numeric variable to LMS

I need to report the value of a variable to my LMS (SuccessFactors). I am using SL3.

I just used basic slides,  not graded or survey questions. I have 3 slides each of which ask the user to select their confidence (Buttons 1-5) and variables set to track what they select. So I have ConfMeter1, ConfMeter2, ConfMeter3. On the last slide, I have triggers that sum up the total of ConfMeter1, ConfMeter2 and ConfMeter 3 and then averages them. The calculations are working, but I need to send that average to the LMS. 

Is there an easier way to do this? Please help!
