Javascript Pulling from LMS API in HTML5

Hi All

I have been playing around with Phil Mayor's code for allowing you to pull the learners name from the LMS however this only works if published in SL2 without HTML5.  Has anyone else had success with this code in 360 and if so did you do anything in particular to get it to work?
