The filter is finally up and running. Thanks for everyone's help. It turns out that openlayers was tagging an extra BBOX to the end of the request. I'm guessing that this kept the filter from executing as it worked just fine when I removed the bbox from the url. Does setcenter place a BBOX at the end of the url? The request I'm now using is a wfs request but I'm puting this into a gml layer and the bbox is no longer an issue. I'll include the request below. I'm not sure if there is a good way to bypass this with a regular wfs filter request but the query is now working the way I had hoped. Thanks again for your help.

So, for example, you might achieve the same result as passing in the following CGI variable to a GeoServer WMS call: CQL_FILTER="attribute > 50" ... by passing the following CGI variable to a MapServer WMS call: MAP_LAYER_0_FILTER="attribute > 50" --j On Thu, Aug 14, 2008 at 3:57 PM, Josh Marcus <[EMAIL PROTECTED]> wrote: Arnd, While MapServer does not support CQL specifically, most CQL filters will work as MapServer filters -- and MapServer filters have some capabilities beyond what CQL will support.

August 2008 17:19 An: [EMAIL PROTECTED] Cc: Openlayers Users List Betreff: Re: [OpenLayers-Users] CQL queries with WFS I used the code below but the map still returned all of the villages. It seems very strange that both my CQL_Filter and URL style filters aren't working. I'm sure I'm missing something but the filter process just doesn't seem to like my queries (at least in terms of the syntax I'm using). The CQL_Filter params did appear in the params section within firebug when I ran it but in a vertical format with each letter listed after a number...so 0 C 1 Q 2 L and so on in a vertical column. I'm not sure if this makes sense or if it is important to the filter problem. Thanks again for your help. If you have any other suggestions about using the CQL_FILTER or a URL style filter please let me know. I've been tinkering with this for quite a while without success so your help is very much appreciated.
