pass variables between Lectora titles

You are going to have problems doing this based on internet security settings when published to a web server. If both courses are in the same directory this would be easier. 

One way around this is to use a common flash file (or a common JS file for cookie saving) to save the cookies and pass it between the courses. The flash file (or JS file) will be 1 directory above, and you load it into each of the courses using an external HTML document.

So the structure would be something like this:

http://mywebaddress.com/commonflash.swf
http://mywebaddress.com/course1/index.html
http://mywebaddress.com/course2/index.html
