Inactive button

I created an inactive button that prevents the user from proceeding to the next screen until the next button appears. In order for the next button to appear I created an action on my audio clip that says "OnDone Playing Show Next" this works fine for single file execution but when publishing to SCORM I receive an OnDone object not supported error. Anyone have ideas on how to work around this? I have tried creating a variable on my audio clip, but it still not working.
