Thanks very much for all
Christopher, I know the code is bad, but I'm creating the functionality first and later y I will "drupalize" my code. :D
I'm very glad of your help, right now, my carousel is rendering by jQuery, finally, I have use the XML version for collect the data, in my callback function return a xml data and this is what I read with $.get() function.
Still I have a dude.
How I can do the function re-execute when I change de select option??
