Dynamic SLD - variable passing problem

[Pascoe,Tim [Burlington]]

I'm working on setting up a dynamically generated SLD, in order to provide user-defined filtering for my application. The SLD is being applied to a virtual OGR layer, from my database. I can do it with a raw request to mapserver by including the SLD= tag, and a path to my php scrip which returns the SLD document. However, when I include the SLD in the metadata for the layer, it seems as if the variable is not passed into the SLD script from the CGI forms. The source for the layer is an OGR/VRT being served as a WMS.

My layer is set up as follows:

  LAYER
    NAME "CABINPoints"
    GROUP "Sample Points"
    STATUS ON
    TYPE RASTER
    TOLERANCE 5
    TOLERANCEUNITS PIXELS
    TEMPLATE "tt.html"
    CONNECTIONTYPE WMS
    CONNECTION "http://localhost/scripts/mapserv.exe?map=C:/Documents%20and%20Settings/TimP/My%20Documents/CABIN/Maps/map/pointswms.map"
    METADATA
          "wms_onlineresource" "http://localhost/scripts/mapserv.exe?"
          "wms_sld_url" "http://localhost/CABIN/Maps/map/study_sld_script.php?study_id=%study_id%"
        "wms_title" "CABIN Points test layer"
        "wms_abstract" "Test Access to CABIN SQL-Server Database on ECBURAS1"
        "wms_srs" "EPSG:42304"
        "wms_name" "CABINPoints"  # Eventually change this to the name of the Project being mapped
        "wms_formatlist" "image/png,image/gif,image/jpeg,image/wbmp"
        "wms_format" "image/png"
        "selected" "0"
        "wms_server_version" "1.1.1"
        "wms_title" "Site Location"
    END
    PROJECTION
      "init=epsg:4326"
    END
    DUMP TRUE
  END

Thanks...
