Hi Richard,

  when I have a look at your getCapabilities doc it seams that you don't 
have queryable layers.

A queryable layer displays the following:

<Layer queryable="1" opaque="0" cascaded="0">
....
</Layer>

Queck your Mapfile....

It could look similar to this (Example for a layer --> TEMPLATE):

LAYER
    NAME "wms_extent"
    STATUS ON
    TYPE POLYGON
    DATA "mydata"

    PROJECTION
       "init=epsg:4326"
    END

    METADATA
       "WMS_SRS"    "epsg:4326"
       "WMS_TITLE"    "WMS Extent"
       "WMS_FEATURE_INFO_MIME_TYPE"    "text/html"
    END


    TEMPLATE "info.html"

    CLASS
       NAME "WMS Extent"
       STYLE
          SYMBOL 0
          COLOR -1 -1 -1
          OUTLINECOLOR 60 60 60
       END
    END

  END # End Layer
