The coding on my phone interferes with the mobile display on my website?

I have had to change form to a more basic one on my website www.openstart.co.uk as the mobile display of the form I paid for doesn't properly display.

This code:

<iframe id="JotFormIFrame-71233029315346" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="https://form.jotformeu.com/71233029315346" frameborder="0" style="width:100%; height:4201px; border:none;" scrolling="no"> </iframe> <script type="text/javascript"> var ifr = document.getElementById("JotFormIFrame-71233029315346"); if(window.location.href && window.location.href.indexOf("?") > -1) { var get = window.location.href.substr(window.location.href.indexOf("?") + 1); if(ifr && get.length > 0) { var src = ifr.src; src = src.indexOf("?") > -1 ? src + "&" + get : src + "?" + get; ifr.src = src; } } window.handleIFrameMessage = function(e) { var args = e.data.split(":"); if (args.length > 2) { iframe = document.getElementById("JotFormIFrame-" + args[2]); } else { iframe = document.getElementById("JotFormIFrame"); } if (!iframe) return; switch (args[0]) { case "scrollIntoView": iframe.scrollIntoView(); break; case "setHeight": iframe.style.height = args[1] + "px"; break; case "collapseErrorPage": if (iframe.clientHeight > window.innerHeight) { iframe.style.height = window.innerHeight + "px"; } break; case "reloadPage": window.location.reload(); break; } var isJotForm = (e.origin.indexOf("jotform") > -1) ? true : false; if(isJotForm && "contentWindow" in iframe && "postMessage" in iframe.contentWindow) { var urls = {"docurl":encodeURIComponent(document.URL),"referrer":encodeURIComponent(document.referrer)}; iframe.contentWindow.postMessage(JSON.stringify({"type":"urls","value":urls}), "*"); } }; if (window.addEventListener) { window.addEventListener("message", handleIFrameMessage, false); } else if (window.attachEvent) { window.attachEvent("onmessage", handleIFrameMessage); } </script>

Hello,

I tested the iFrame code on an empty HTML file and it is working properly:

Please, try getting a fresh iFrame code from JotForm publish section and embed the form into your website. After that contact us again. We need to investigate the issue on your website, in order the find the cause of the issue.

We are awaiting your response.

Thank you very much.
