Bill, Here is something that I have tested in 5.2
http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/workshop08/runtime_s ub_config.map&mode=map&map.layer[counties].class[0].style[0]=COLOR+178+3 4+34+WIDTH+3 It changes both the color and width of the line feature, just drop the '+WIDTH+3' off of the end. Also, I recommend testing your substitution like this directly in the URL before attempting to pass it from OpenLayers.

In OpenLayers, I have to format the parameter as a key: value pair. So here's what I've tried (without success) in my OL javascript: var baseLayer = new OpenLayers.Layer.MapServer( "USA", "http://206.168.217.244/cgi-bin/mapserv?";, { map_imagetype: 'PNG', layer: 'states', map_layer_0_class_0_style_0_color: '255+255+000', map: '/var/www/html/piper/usa.map' }, { singleTile: true }); If I take out this line: map_layer_0_class_0_style_0_color: '255+255+000' the map works fine. The only layer in the map is the US states, and all I want to do is change the color from pale yellow as set in the map file to bright yellow. The relevant part of the map file looks like this: LAYER NAME "states" TYPE POLYGON DATA states CLASS NAME "US States" STYLE OUTLINECOLOR 100 100 100 COLOR 255 255 192 END END PROJECTION "init=epsg:32614" # UTM Zone 14 N WGS84 END STATUS DEFAULT END I think the problem is that I've got the syntax wrong in trying to override the MapServer map file parameter. I've looked at http://mapserver.osgeo.org/cgi/controls.html#changing-map-file-parameter s-via-a-form-or-a-url but that hasn't helped. So does anyone *here* know how to do this? (I was told on the OpenLayers mailing list to try asking on the MapServer list.)
