Preview in browser not working - nor when published to a web server

[#1]

My project has two pertinent slides. One includes buttons that execute Advanced Actions, and the other slide includes a number of objects including text, shapes, and clickboxes. Several Advanced Actions control a lot of logic that refreshes and changes the main slide. 

Clicking button A executes an Advanced Action to jump to the main slide, sets some variable values, and shows or hides about a dozen or so objects. But in HTML preview, or when launching from a web server, nothing happens when I click button A.

In regular non-HTML preview, everything works fine.

Is it possible that some complexity in the Advanced Actions are causing a problem?

What should I check in my browser settings - Chrome especially?

Testing in Firefox also did not work.

Any thoughts most appreciated.

Well, I began disecting that Advanced action and found the problem, which as something to do with parsing double-quotes. That line reads:

Assign  |  v_sf_msg with ""ad" says/ad/"

Note that I entered that value as:

"ad" says /ad/

And the outer quotes were added by Captivate, which makes sense. When I removed my quotes and entered this:

ad says /ad/

Captivate added outer quotes like this:

"ad says /ad/"

That ran perfectly.  So, there is a parsing issue and I'll just work around that for now.

Thanks!

That is the reason I often replace literals by user variables with a default value.
