Unable to apply CSS PIE style to IE.*

Question

I'm having trouble getting CSS PIE to work with IE 6-8 (9-10 untested). I'm trying to get the "selected" style to apply. Can anyone see where this is going wrong?

Cheers

chrome+ff - fine

ie result = bad

   <div class="tabBox">
        <ul class="tabs">
            <li id="step1" class="selected"><a href="#"><span class="tabTitle">STEP 1:</span><span class="tabSubtitle">Step 1</span></a></li>
            <li id="step2"><a href="#"><span class="tabTitle">STEP 2:</span><span class="tabSubtitle">Step 2</span></a></li>
            <li id="step3"><a href="#"><span class="tabTitle">STEP 3:</span><span class="tabSubtitle">Step 3</span></a></li>
        </ul>

Pie requires the properties being polyfilled to be prefixed with -pie-, so you should write:

.tabBox .tabs .selected a 
{
background: -ms-linear-gradient(top,  #cbc3b7 0%,#c4bdb1 84%,#000000 100%);
-pie-background: linear-gradient(top,  #cbc3b7 0%,#c4bdb1 84%,#000000 100%);
background: #ece9e6;
-webkit-box-shadow: #CCC 0 0 .25em;
-moz-box-shadow: #CCC 0 0 .25em;
-pie-box-shadow: #CCC 0 0 .25em;
box-shadow: #CCC 0 0 .25em;
}
