keep form open when there are errors

I am using trhe followinf jQuery to hide the form apart from the header of the form:

jQuery('#primary .gform_wrapper').not('.page-contact-us #primary .gform_wrapper').hide();

		jQuery("#primary .gform_widget h3").click(function(){
		// slide toggle effect set to slow you can set it to fast too.
		jQuery('#primary .gform_wrapper').slideToggle("slow");
		return true;
		});

When a form errors ie a field is missed is there a way to capture that so i can make sure the form is not closed and hidden ?

I would prefer to do that but when a form uses AJAX it pits the script tags onto the page and then it doesnt validate in HTML5 :(

In most circumstances I would not mind if it doesnt validate as you say because it still functions and still falls back nicely but in this case it is a requirement from the client that it needs to validate. Believe me I have spoken to them at length on the subject but because they are promoting the fact the site is all singing and dancing they want to have everything working prefectly and all validating.

Thanks for the update I am looking forward to the next release :)
