Need to pass storyline variables in a url

I'm new in my current organization and the first eLearning that I developed need to interact with a custom LMS here. I have the learners enter their pc ID, first and last name in the Intro slide. I need to pass these values in a url at the end of the module. My question is do I need to create variables in javascript to capture these values, store them in the url, and then use the openwebobject function. Kindly help. I recommended Storyline for in-house development and we purchased it too. Don't want to let people down. Please help.

Thanks,
U
