Menu Not Showing up on iPhone [SOLVED]

Hi Guys,
I have just finished a site and finishing off the responsive side and can across this issue.
The CSS Menu wont show up in an iPhone on the front page only . I also use responsivedesignchecker.com/stringline.virtualbean.com.au when developing and it looks fine in there, but when testing on an actual iPhone I get a slim line with no menu.

I have change the the style of the menu back to Black & White for testing.
The site is http://stringline.virtualbean.com.au/

Any assistance would be appreciated
Thanks
Wayne

Hi NT,
Thanks again for your quick response.
I tried that but it still would not open properly on an iPhone.
I discovered that I had a fixed height in one of the other class, once i removed this it was all fine

Thanks Again
