SLD TextSymbolizer Question

[Pascoe,Tim [Burlington]]

        I've been working on a way to incorporate a dynamically generated SLD, which I am using to provide custom filter capabilities on a point layer. I've managed to get a simple widget (using Chameleon) developed which passes a form variable to the SLD script file, permitting a dynamic filter value to be passed. It works great, but now I'm having trouble getting the TextSymbolizer in the SLD to correctly format the labels.

        The TextSymbolizer will change the color of the labels, but not the font or the point size - the font is installed with Mapserver in the correct directory. The map file layer, and appropriate SLD script is below.

Thanks for any suggestions - I'm sure I'm missing something simple......

Here is the extract of the TextSymbolizer script:

$strScriptOut = $strScriptOut . "                             <TextSymbolizer>";
$strScriptOut = $strScriptOut . "                               <Geometry>";
$strScriptOut = $strScriptOut . "                                 <PropertyName>site</PropertyName>";
$strScriptOut = $strScriptOut . "                               </Geometry>";
$strScriptOut = $strScriptOut . "                               <Label>site</Label>";
$strScriptOut = $strScriptOut . "                               <Font>";
$strScriptOut = $strScriptOut . "                                 <CssParameter name='font-family'>vera</CssParameter>";
$strScriptOut = $strScriptOut . "                                 <CssParameter name='font-style'>normal</CssParameter>";
$strScriptOut = $strScriptOut . "                                 <CssParameter name='font-weight'>normal</CssParameter>";
$strScriptOut = $strScriptOut . "                                 <CssParameter name='font-size'>8</CssParameter>";
$strScriptOut = $strScriptOut . "                               </Font>";
$strScriptOut = $strScriptOut . "                               <Fill>";
$strScriptOut = $strScriptOut . "                                 <CssParameter name='fill'>#000000</CssParameter>";
$strScriptOut = $strScriptOut . "                               </Fill>";
$strScriptOut = $strScriptOut . "                               <LabelPlacement>";
$strScriptOut = $strScriptOut . "                                 <PointPlacement>";
$strScriptOut = $strScriptOut . "                                   <AnchorPoint>";
$strScriptOut = $strScriptOut . "                                     <AnchorPointX>0.5</AnchorPointX>";
$strScriptOut = $strScriptOut . "                                     <AnchorPointY>0.5</AnchorPointY>";
$strScriptOut = $strScriptOut . "                                   </AnchorPoint>";
$strScriptOut = $strScriptOut . "                                   <Displacement>";
$strScriptOut = $strScriptOut . "                                     <DisplacementX>20</DisplacementX>";
$strScriptOut = $strScriptOut . "                                     <DisplacementY>10</DisplacementY>";
$strScriptOut = $strScriptOut . "                                   </Displacement>";
$strScriptOut = $strScriptOut . "                                   <Rotation>20</Rotation>";
$strScriptOut = $strScriptOut . "                                 </PointPlacement>";
$strScriptOut = $strScriptOut . "                           </LabelPlacement>";
$strScriptOut = $strScriptOut . "                               <Halo />";
$strScriptOut = $strScriptOut . "                         </TextSymbolizer>";


Here is the Mapfile layer:
