Yes, the paypal function works because I commented out 'chosen.js' javascript. But this then means the mobile nav does not function. It hovers but wont open the nav. Please see here for example - http://tommyanderson.co.uk/milamase/childrenswear/babidu-royal-blue-romper.html
If I leave the chosen.js as per your template, it adds a search area which is not needed (see screenshot):
Please help!
