date picker doesnt work / doesnt re-direct to confirmation screen.

Please begin by checking for theme and plugin conflicts by following these instructions:

You have a fairly unique theme there and when the date picker does not work, it's normally due to a JavaScript or jQuery error. The first step is to see if there is a conflict with the theme or a plugin.

Going back to stevem802002's original problem: this looks like a Themeforest theme and they usually include the [raw] shortcode. That affects the processing of all other shortcodes, including Gravity Forms. If you check the source of the page, you will see that the Gravity Forms output has been modified with additional HTML markup. Screenshot: http://minus.com/lyhjwG3R7niOB

I think that is breaking the functionality. You can try wrapping the [gravityforms] shortcode in the [raw]shortcode[/raw] and see if that fixes the problem.

Here is some additional discussion about the [raw] shortcode:

Thanks for the update.
