Menu button "Bauhaus" doesn't work

Hi, trying to get the mobile site for exeter-kitchens.co.uk to work but I’m stuck on the menus not coming up. It all looks a bit boring as I haven’t uploaded any icons etc for it so don’t judge it, but if the menu won’t work it would be a waste of time! Thanks for any help you can give me. Running up to date wordpress and wptouch. Thanks
