I am unable to move to next module at the end

As I understand it, your Next button doesn't advance from the last slide in a module to the first slide in the following module.

Are you using "module" to refer to a Scene in Storyline? If so, there's an easy fix:

• Edit the trigger for the Next button so it jumps to the next scene (instead of the next slide). Or have it jump to a specific slide (for example, slide 2.1, which would be the first slide in the scene 2).

Why? The "jump to next slide" trigger only works within a scene. A Storyline course can branch in many ways. So, at the end of a scene, you have to specify exactly where "next" is. 

Are you using "module" to refer to 2 sets of published files (for example, published from 2 different Storyline files)? There's no easy fix for that. Storyline isn't set up to launch a separate course in an LMS.  

By the way, I suggest you test your entire course before you upload it into an LMS. You can do that using the Preview function or by publishing it to Review 360. Either way allows you to step through the course to ensure that everything works as expected.
