Problem with Firefox and Safari

Dear,
I've evaluated free version of slider on IE 9.0 and all it works fine.

But I've strange problem with Firefox and Safari, the slider didn't work.
Then I've insert alert(err) in catch(err) of your slider code.

In Firefox 12.0 have this javascript error:
TypeError: h7[o.name] is undefined

In Safari 5.1.7 have this javascript error:
TypeErrore undefined is not a object

I've try to change jquery-1.7.1.min with jquery-1.8.2.min but I didn't resolved.

Can I help me to investigate this error ?

Thanks,
Rinaldo
