When I enter in the code:
?wmode=opaque&bgcolor=#ffffff&scale=default" class="floatbox" data-fb-options="width:775 height:450 scrolling:no"

for some reason it cuts off at scale=default"
therfore it does not get to class ="floatbox"

but I can get it to work on a different sub directory?

Some other javascript on that page is overwriting all the class names in the unordered list with class="f_right". You can work around this by setting the rel attribute instead of the class for floatbox.
rel="floatbox"
