Mobile Ready Issues

Image 26 is a grayed out picture that is supposed to look like an inactive button that disappears and shows the actual continue button after the video has completed.  Overlaying Image 26 is a Button that says "you must watch this full video to continue".  After the video completes, both are supposed to disappear and reveal an "active" continue button. This works on a desktop version, however, is not working in the mobile ready format on my iPhone (i.e. the button will not go green and will remain grayed out.  Also the button will allow me to advance without considering the properties I've configured here).  Any ideas?  thanks!
