将谷歌广告词跟踪与salesforce相结合

im正试图基于此将谷歌广告词跟踪与salesforce集成https://www.e-nor.com/blog/google-analytics/integrate-salesforce-and-google-analytics

我在salesforce中创建了隐藏字段，并将代码添加到表单和js脚本中以捕获值，但我遇到了问题，我没有在中获得任何数据

test.php?utm_source=google&utm_medium=CPC&utm_campaign=test&utm_term=test
<input type="hidden" name="medium" id="medium" value="" />
<input type="hidden" name="source" id="source" value="" />
<input type="hidden" name="campaign" id="campaign" value="" />
<input type="hidden" name="term" id="term" value="" />

<script type="text/javascript">
var z = _uGC(document.cookie, '__utmz=', ';');
var source = _uGC(z, 'utmcsr=', '|');
var medium = _uGC(z, 'utmcmd=', '|');
var term = _uGC(z, 'utmctr=', '|');
var content = _uGC(z, 'utmcct=', '|');
var campaign = _uGC(z, 'utmccn=', '|');
var gclid = _uGC(z, 'utmgclid=', '|');
if (gclid !="-") {
 source = 'google';
 medium = 'cpc';
}
var csegment = _uGC(document.cookie, '__utmv=', ';');
if (csegment != '-') {
 var csegmentex = /[1-9]*?'.(.*)/;
 csegment = csegment.match(csegmentex);
 csegment = csegment[1];
} else {
 csegment = '';
}
function _uGC(l,n,s)
{
if (!l || l=="" || !n || n=="" || !s || s=="") return "-";
var i,i2,i3,c="-";
i=l.indexOf(n);
i3=n.indexOf("=")+1;
if (i > -1) {
i2=l.indexOf(s,i); if (i2 < 0){ i2=l.length; }
c=l.substring((i+i3),i2);
}
return c;
}
document.getElementById("medium").value =medium; /* Campaign_Medium */
document.getElementById("source").value =source; /* Campaign_Source */
document.getElementById("campaign").value =campaign; /* Campaign_CampaignName */
document.getElementById("term").value =term; /* Campaign_Term */
</script>
