Problem to display PPC advertising

I use this code for “PPC” advertising:

<script type="text/javascript">
;!( function( w, d ) {
'use strict';
var ad = { user: "11111", width: 120, height: 240, id: 'anetwork-' + ~~( Math.random() * 999999  ) },
h = d.head || d.getElementsByTagName( 'head' )[ 0 ],
s = location.protocol + '//static-cdn.anetwork.ir/aw/aw.js';
if ( typeof w.anetworkParams != 'object' )
w.anetworkParams = {};
d.write( '<div id="' + ad.id + '" style="display: inline-block"></div>' );
w.anetworkParams[ ad.id ] = ad;
d.write( '<script type="text/javascript" src="' + s + '" async></scri' + 'pt>' );
})( this, document );</script>

But I have one problem. If I insert code in to the wordpress widget doesn’t work and if I insert in index.php (or page.php , single.php ,…) works!!
note : error in inspect element >> console (When I insert code in wordpress widget)

Uncaught SyntaxError: Unexpected token ILLEGAL : "mysite.com/:253
Failed to load resource: the server responded with a status of 404 (Not Found) : http://mysite.com/'%20+%20s%20+%20'

line 253 :
d.write( '</script><script type="text/javascript" src="' + s + '" async>' );
What is the problem?
