Form Layout Issues

Right now I don't see a form on that page you linked to. So i'm not sure what you are talking about.

If you are having an issue it's likely going to be CSS style related. I do also see a Javascript error on that page that is unrelated to Gravity Forms that you'll want to look at. See this screenshot:

The Javascript error I mentioned above is still there. I do see your form now.

The problem is the necessary Gravity Forms scripts and CSS are not being output on your page. That is why the form is unstyled and the datepicker isn't working properly. The necessary scripts aren't there.

This is either going to be because of either...

1) You have script output turned off on the Settings page of Gravity Forms or

2) Your theme doesn't have the necessary WordPress header and footer hooks in place.

Your theme needs to have the wp_head() function call in the header.php and the wp_footer() function call in the footer.php file. These are used by plugins to output scripts and CSS in the header and footer of your site. If they aren't there, plugins cannot do this.

Is this a custom theme, free theme or a theme you have purchased?

One way to tell right away if it's a theme issue is going to be to activate the default Twenty Eleven theme and then view this page.
