How to add a Javascript library ?!

[Melaga]

Thank you Gordon. Finally the first method you explained is working( using the web page object).
But I would like to get the the second one working (using the html object).

How can I make the html object(code) to use snap js library? If I import the snap Js library file into the Hippo library, Would the html object automatically find it from hippo library  Or would I need to assign any script ids ?!
could you please elaborate on this topic?

Or Would I need to add the snap js library to the General js section in a movie?

In the library menu, choose "Script File", copy and paste the snap js library code into this file.
Hopefully, you can then use is in Hippo, as long as there are no conflicts, e.g. the snap file uses a variable the same name as hippo.

Thank you Gordon,
Here is the Hippo hani file:

I've followed what you instructed but it still only shows the js code when exporting it to html.
