JumpMenu PHP - Label

Hello everyone adobe community!

I'm in trouble and know that everyone here has experience with this to help me.
Below is the code

<script type="text/javascript">

<!--

function MM_jumpMenu(targ,selObj,restore){ //v3.0

  eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");

  if (restore) selObj.selectedIndex=0;

}

//-->

</script>

<form name="form" id="form" action="">

  <select name="select2" id="jumpMenu" onchange="MM_jumpMenu('parent',this,0)" class="styled" style="margin:30px 0 0 685px; width:80px; float:left;">

    <option value="imprensa.php">2011</option>

    <option value="imprensa-em-2010.php">2010</option>

    <option value="imprensa-em-2009.php">2009</option>

    <option value="imprensa-em-2008.php">2008</option>

  </select>

</form>

My question is as follows:

When I click on the imprensa-em-2010.php would like the option label 2010 writes, because it returns the first label is 2011.
And so with the other items below
This is a jumpMenu because when I click on 2008 for example he gives me a page properly impresa-em-2008.php just right over the label instead of writing in 2008, he returns to 2011.

I thank everyone's understanding.
God bless you.
