  <a href="https://www.test.be/fr_BE/home/forms/test-test-salon.html?configId=f4q8s9z1&amp;ucpBaseurl=https%253A%252F%252Ftest.client.ucp.cloud&amp;model=F56&amp;motorization=Diesel" rel="nofollow noreferrer">https://www.test.be/fr_BE/home/forms/test-test-salon.html?configId=f4q8s9z1&amp;ucpBaseurl=https%253A%252F%252Ftest.client.ucp.cloud&amp;model=F56&amp;motorization=Diesel</a></p>
  
  <p>The part I want to isolete is the model id, model=F56, in this case I want to isolate "F56"</p>
  
  <p>I tried this script without success:</p>
  
  <pre><code>var srcID = "11111"; // Insert your src ID here
  var typeID = "11111"; // Insert your type ID here
  var category = "m1111"; // Insert your category value here
  var axel = Math.random() + ""; var a = axel * 10000000000000;
  
  // Grab Data Layer
  var dataLayerApi = digital.tracking.getInstance(dataLayer);
  var digitalData = dataLayerApi.getPageObject((window.minidtm.actPageId     !== undefined) ?  window.minidtm.actPageId  : dataLayerApi.getCurrentPageIndex());
  
  var path = document.location.pathname;
  var pathHirarchy = path.split("&amp;");
  
  if(path.match("\/fr_BE\/home\/forms\/.*\/.*") != null) {
              // Get Model Info
              var u1 =  pathHirarchy[1] //U1 - Produit
              var u2 =  pathHirarchy[5].split(".")[0] //U2 - Sous Produit
  }
  else {
  
   var u1 = "notApplicable";
   var u2 = "notApplicable";
  }
  
  var DCtag = document.createElement("iframe");
  DCtag.src = "https://" + srcID + ".fls.test.net/activityi;src=" + srcID + ";type=" + typeID + ";cat=" + category +
          ";u1=" + u1 +";u2=" + u2 + ";dc_lat=;dc_rdid=;    tag_for_child_directed_treatment=;ord=1;num=" + a;
  DCtag.width = "1"; DCtag.heigth = "1"; DCtag.frameborder = "0"; DCtag.style =    "display:none"; DCtag.async = true;
  document.body.appendChild(DCtag);
  </code></pre>
