I need several drop-down list on a web page. Each of these drop-down lists should redirect when a new item is selected. Here is my code ...

This first one works perfectly...
<select name="NavSelect" onchange="Navigate(this.form)">
<option value="2008">2008</option>
<option value="cal2007.htm">2007</option>
<option value="cal2006.htm">2006</option>

However, the second two do not. They go to a blank page instead of the page indicated in the code. I'm sure I'm missing something simple.

<td style="width: 41px">May</td>
<td style="width: 31px" class="style5">
<select name="NavSelect2" onchange="Navigate(this.form)">
<option value="Management">Management</option>
<option value="awardsMay08.htm">Awards</option>
<option value="openingsMay08.htm">New Openings</option>
<option value="proposalsMay08.htm">Proposals</option>

<td style="width: 116px" class="style5">
<select name="NavSelect3" onchange="Navigate(this.form)">
<option value="Tech">Tech</option>
<option value="mayMtg.htm">Video</option>
<option value="This%20is%20a%20Test.mht">Slides</option>

Any help with this ASAP would be greatly appreciated!!! Thanks!
