Custom code not working on non-home pages

Hi

I’m trying to get to the bottom of a strange problem on my clients website mortgagesforselfemployed.co.uk.

We run Google paid search ads to it and we’re trying to track offline conversions by grabbing Google’s gclid parameter value on the landing page, and passing it through to an embedded typeform at mortgagesforselfemployed.co.uk/dyq

The problem is the custom code our dev has implemented only seems to work on the home page and not on any of our PPC landing pages like: Get A Self Employed Mortgage | Free Quotes - Call Now

The developer is adamant it’s a weird glitch in webflow itself. We’ve contacted webflow support but they say custom code support is outside their remit.

Here’s the amended embedded html on the /dyq page:

<script>
    const urlParams = new URLSearchParams(window.location.search);
    const myParam = urlParams.get('gclid');
    console.log(myParam)
    var url = "https://leadenquiry.typeform.com/to/MCVudW?typeform-medium=embed-snippet#gclid="+myParam+"&source=";
    window.onload = (event) => {
        var ifrm = document.createElement("iframe");
        ifrm.id = 'typeform-full';
        ifrm.setAttribute("src", url);
        ifrm.width = "100%";
        ifrm.height = "100%";
        document.body.appendChild(ifrm);
    };
</script>
<script type="text/javascript" src="https://embed.typeform.com/embed.js"></script>

And here’s the global javascript code in the custom code footer section in Project settings:

<script>

        // create urlParams variable (constant) from URLSearchParams class using current window
           const urlParams = new URLSearchParams(window.location.search);
          
        // set UTM medium, source and campaign variables (constants) based on results of URSearchParams
           const utm_medium = urlParams.get('utm_medium')
           const utm_source = urlParams.get('utm_source')
           const utm_campaign = urlParams.get('utm_campaign')
           const gclid = urlParams.get('gclid')

        // get the RSVP button element
           	var rsvpLink = document.getElementById("rsvp");
  			var rsvpLink1 = document.getElementById("rsvp1");
  			var ttq3 = document.getElementById("ttq3");
  			var tooq4 = document.getElementById("tooq4");
  			var tooq5 = document.getElementById("tooq5");
            var tooq6 = document.getElementById("tooq6");
            var tooq7 = document.getElementById("tooq7");
            var tooq8 = document.getElementById("tooq8");
            var tooq9 = document.getElementById("tooq9");

        	// edit RSVP button element property by appending the URL parameters
           rsvpLink.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
 		 	// edit rsvp1 button element property by appending the URL parameters
           rsvpLink1.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  			// edit TTQ3 button element property by appending the URL parameters
           ttq3.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  			// edit TOOQ4 button element property by appending the URL parameters
           tooq4.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  			// edit TOOQ5 button element property by appending the URL parameters
           tooq5.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  // edit TOOQ6 button element property by appending the URL parameters
           tooq6.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  // edit TOOQ7 button element property by appending the URL parameters
           tooq7.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  // edit TOOQ8 button element property by appending the URL parameters
           tooq8.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
  // edit TOOQ9 button element property by appending the URL parameters
           tooq9.href += "/?medium=" + utm_medium + "&source=" + utm_source+ "&campaign=" + utm_campaign+ "&gclid=" + gclid;
  
        // log final RSVP button link to console
           console.log(rsvpLink.href);
  			console.log(tooq9.href);

HI @GrahamCox you should tell your developer that there are errors on pages that should be revisited and fixed

Home Page

DYQ page

I didn’t checked other pages but fixing these errors can be good starting point :wink:

Hi @Stan

My sincere apologies for the late reply and thank you for taking the trouble to do this. I’ve passed it onto my developer for his attention.

Thanks again,

Graham
