[Plugin: Google Content Experiments] Error when validating code

I’ve checked your experiment code and found differences (underscores) with two experiment code snippets I’m using myself.

I’ve adjusted your code. Try using the code below and see if you get your experiment validated:

<script>function utmx_section(){}function utmx(){}(function(){var
k='132090-0',d=document,l=d.location,c=d.cookie;
if(l.search.indexOf('utm_expid='+k)>0)return;
function f(n){if(c){var i=c.indexOf(n+'=');if(i>-1){var j=c.
indexOf(';',i);return escape(c.substring(i+n.length+1,j<0?c.
length:j))}}}var x=f('__utmx'),xx=f('__utmxx'),h=l.hash;d.write(
'<sc'+'ript src="'+'http'+(l.protocol=='https:'?'s://ssl':'://www')+'.google-analytics.com/ga_exp.js?'+'utmxkey='+k+'&utmx='+(x?x:'')+'&utmxx='+(xx?xx:'')+'&utmxtime='+new Date().valueOf()+(h?'&utmxhash='+escape(h.substr(1)):'')+'" type="text/javascript" charset="utf-8"><\/sc'+'ript>')})();
</script><script>utmx('url','A/B');</script>
