Thanks for the feedback and explanation.
I moved the speaker image to the CSS folder and it now displays correctly. I uploaded the missing jquery.mobile-1.3.2.min.js and now the sound plays correctly and the background color changes also, this can be seen here http://www.lawenforcementspanish.com/mle2 then select the Age/Weight/Height menu item. However I noticed that when I added the ....1.3.2.min.js library the menu page formatting changed - the original and correct formatting can be seen here http://www.lawenforcementspanish.com/mle . I have no idea what caused the formatting change.
Regarding the appmobi.js - yes that's needed for the mobile app as far as I understand so I think I should leave it in.
As for the multiple jQuery/ jQuery Mobile links you highlighted in red they came from the jQuery Mobile template in Dreamweaver. I tried commenting them out here http://www.lawenforcementspanish.com/mle3 but as I suspected I lost all formatting of the menu page so I think they have to stay.
I'm at a bit of a loss to know what I should try next, it feels as though we're almost there in the mle2 version, above, if only I could get back the original formatting as shown in the mle version.
Thanks again for your assistance with this, I truly appreciate your time and patient explanations.
