Widget problem

[Moderator Note: Topic title amended. Your problem is no more urgent than anyone else’s.]

Hello all,
This is my first post here, so apologies if I am posting this in the wrong section.
The problem I have is on the website http://www.greekagribusinessawards.gr
As you can see on the left had side is a small menu (just two options, Organizers and Contact Us). As you can see it’s in two language, english and greek.
This menu was created in a widget. The complete code within the widget is:

var thisLocation = window.location.href;
var thisLocationEn = thisLocation.search("/en/");

if(thisLocationEn != "-1") {

document.write('<div style="color:black;padding-bottom:40px;width:150px;margin:0 auto;font-size:16px"><img src="/gtf2013/wp-content/themes/gaf2013/images/GAgroF_velos_portokali.png" /><span style="padding-right: 10px;padding-left: 5px"><a href="'+thisLocation+'diorganwtes">ORGANIZERS</a></span><img src="/gtf2013/wp-content/themes/gaf2013/images/GAgroF_velos_portokali.png" /><span style="padding-left: 5px"><a href="'+thisLocation+'contact-form">CONTACT US</a></span></div>');

} else {

document.write('<div style="color:black;padding-bottom:40px;width:150px;margin:0 auto;font-size:16px">
<img src="/gtf2013/wp-content/themes/gaf2013/images/GAgroF_velos_portokali.png" /><span style="padding-right: 10px;padding-left: 5px"><a href="'+thisLocation+'diorganwtes">ΔΙΟΡΓΑΝΩΤΕΣ</a></span>
<img src="/gtf2013/wp-content/themes/gaf2013/images/GAgroF_velos_portokali.png" /><span style="padding-left: 5px"><a href="'+thisLocation+'contact-form">EΠΙΚΟΙΝΩΝΙΑ</a></span></div>');

}

Can someone please helm me out and tell me what I am doing wrong?
