VBA to click a tab on a website

[bmacias]

I'm trying to click on a tab that says Region from a website. Here's the source code:

<div id="ctl00_plc_RadTabStrip1" class="RadTabStrip RadTabStrip_Default RadTabStripTop_Default RadTabStripTop" style="margin-left: 10px; margin-top: 10px;">
<div class="rtsLevel rtsLevel1">
<ul class="rtsUL">
<li class="rtsLI rtsFirst" style="width:110px;"><a class="rtsLink rtsBefore" href="#"><span class="rtsOut"><span class="rtsIn"><span class="rtsTxt">Region</span></span></span></a></li>
<li class="rtsLI" style="width:110px;"><a class="rtsLink rtsSelected" href="#"><span class="rtsOut"><span class="rtsIn"><span class="rtsTxt">District</span></span></span></a></li>....blah, blah, blah

I've tried

IE.document.all("ctl00_plc_RadTabStrip1").selectedIndex = 0
IE.document.all("ctl00_plc_RadTabStrip1").FireEvent ("onchange")

to no avail. How do I go about coding it to select it?

Thank you in advance.
