Fixed nav bar issues

Hi there,

I am tearing my hair out with this one, I have created a fixed nav and want to create a slider hero yet it disappears under the nav , cutting off 150/200 pixels off the hero. http://raob.webflow.com

I made a similar site with the same design which it worked fine on [ have checked the settings / navigator are the same which i think they are ] yet was wondering if there is a bug of sorts ? am getting really frustrated with this

its ok , had to add a margin at the top , should of watched a tutorial video… doh !
