I have a drop down menu that I can't get to open in a new window. I have set the target to blank with no luck. Here is my code:

<form name="TopicCompass" target="_blank" class="">
<div>
<div align="center"><span class="style31">Retail Compass</span> <br>
<select name="menu" onChange="location=document.TopicCompass.menu.options[document.TopicCompass.menu.selectedIndex].value;" value="GO">
<option>Select a Plan</option>
<option value="http://..Teller_Plan.pdf">Teller</option>
<option value="http://..FSR_Plan.pdf">FSR</option>
<option value="http://..PB_Plan.pdf">Personal Banker</option>
</select>
</div>
</div></form>


Any help would be much appreciated!
