Slider jQuery UI

Slider jQuery UI

Hello ,

I need your help,

I would like to use the slider of jQuery UI to make a credit simulator.
I succeed to configure it BUT I don't find if it's possible to limit it.

In fact, I'd like to make a simulator like this : http://www.opel.be/fr/Configurator/Agila/Start.aspx#step2
If you click on step 2 , there are 2 simulators and I need to make the sames for my customer.

If someone can help me, thanks in advance
