storm vars and teb

Hi i want to grab the short text that a user might type into a captivate 8 text box which I named "teb1"

and send it to the the LMS. In this case to the comments.

var ty=teb1.text

var text_box1 = SCORM_CallLMSSetValue('cmi.comments', ty);

this is not working, has anyone tried to do this?
