The solution to this ended up being very simple.
Even though previewing worked fine, running a published local or published internal server copy would not function.
I needed to put it out on the web in order for it to work.
That is good news but burdensome nonetheless because I am not a web admin - I am a content developer and build learning interactions so I don't have website admin rights - gotta wait for someone to upload for me and then I can test them.
I am excited, though, to see that I can get Captivate and Greensock working together.
Now that the proof of concept is made - I can petition for the business license. Wish me luck!
