Drop down menu target

[poulou]

Hello everyone, first post here!

I ve made a drop down menu at my site poulou.50webs.com/

The menu is at an other frame and I cannot make it change the main frame... any ideas...?

<form name="jump" target="main">
<select name="menu" onChange="location=document.jump.menu.options[document.jump.menu.selectedIndex(here is the problem, I believe)].value;" value="GO">
<option value="http://dvd.stuff.gr/" style="background: url(images/site_img/stuff.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dvd.Stuff</option>
<option value="http://cinetalk.pblogs.gr/" style="background: url(images/site_img/cinetalk.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;CineTalk</option>
<option value="http://www.greektvsubs.gr/" style="background: url(images/site_img/greektvsubs.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GreekTvSubs</option>
<option value="http://www.greeksubs.com/" style="background: url(images/site_img/greeksubs.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;GreekSubs</option>
<option value="http://www.ripit4me.org/" style="background: url(images/site_img/ripit4me.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;RipIt4Me</option>
<option value="http://www.insomnia.gr/" style="background: url(images/site_img/insomnia.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insomnia</option>
<option value="http://www.adslgr.com/" style="background: url(images/site_img/adslgr.PNG) no-repeat scroll left center;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;AdslGr</option>
</select>
</form>

Edit: something else... the backgrounds of the options are not displayed at IE6 but its ok at Firefox..
