Everything works well until I get to the paypal button (in wrapper mode) when I click it it goes nowhere. Without the wrapper the script works fine and I guess you will say that this is a problem with joomla 1.4.22 /23 (I have changed the versions but at no effect) and that is nothing you can do about it but I thought I just try in case you were aware of a tweak to the papal script within C2 which may solve the problem. 

If you do let me know!
