datepicker & IE8

datepicker & IE8

Hi everyone

i'm developing a facebook app and i've some trouble in using it with IE8.
The idea is that i have to develop a form, that has got 3 datepicker linked to 3 input text.
In firefox, safari and chrome this app works well, but in IE8 the calendar doesn't appear when i click
in the input text.

I don't really know what to do to make it works.

In attach you can find the source of my app.

Thanks to all

Gaetano
