HTML5 builder jQuery datetime picker

HTML5 builder jQuery datetime picker

Hi
I am using HTML5 builder to build a server side database reporting system. I need to have client side users enter dates using a datetime picker but the picker that comes with HTML5 builder does not work on most browsers.
The jQuery picker would be perfect and while I can get it to work in an html document I cannot get it to work on the HTML5 builder php pages.
I am very new to JAVA script so do not really know where to start.
Does anyone have any ideas how I can go about this?
Thanks
Jerry
