We're having some difficulty with the dependent options not displaying on Apple iPhone/iPad - not sure if they are displaying for other mobile versions. They do display on our computers (Win7 and Win10) in both Chrome and IE.
Hi Lynne I tried your site on firefox and had problems with the dependent options. So I had a look at the javascript file and that was from June last year which is quite old so I did a <Ctrl>+Refresh to force a refresh and got the current JS file. So I think the JS file may have been cached and I tried on my iPhone and that is fine (as I probably hadn't visited the site before). Can you try a refresh in iPhone and see if that helps?
