I tried that, heres my complete funktion:


function checkinfo(imgid,url,title){

if (infobox == 0) {infobox = 1;}
if (imgid == oldimgid) {infobox = 0;}
id = imgid.substring(3,imgid.length);
	 if(infobox == 1 && document.getElementById(id).checked==true) {
	 					document.getElementById('map').style.cursor = 'crosshair';
						document.getElementById(imgid).src = "img/treemenu/identify_2.gif";
        		if (oldimgid != null) document.getElementById(oldimgid).src =
"img/treemenu/identify_1.gif"; 
        		oldimgid = imgid;
        		document.getElementById('nodeList').style.visibility = 'visible';

    map.events.register('click', map, function (e) {
				if(infobox == 1 && document.getElementById(id).checked==true) {
	 					document.getElementById('map').style.cursor = 'crosshair';
            OpenLayers.Util.getElement('nodeList').innerHTML = "Loading...
please wait...";
            var coords = window[id].map.getLonLatFromPixel(e.xy.x, e.xy.y);
			var request =  window[id].getFullRequestString({
                            q_type: "0",
                            extent: window[id].map.getExtent().toBBOX(),
                            coords: coords.lon+","+coord.lat, 
			},
						
"http://172.21.18.45/ka-map/map_query_float.php?map=geoland_test&groups=Abflussstation");
            OpenLayers.loadURL(request, '', this, setHTML);
            OpenLayers.Event.stop(e); 
				}
      });
		}
else {		
	 					document.getElementById('map').style.cursor = 'auto';
			 			document.getElementById('nodeList').style.visibility = 'hidden';
			 			if (imgid == oldimgid) { oldimgid = null; } else { oldimgid = imgid;
}
						document.getElementById('nodeList').innerHTML = "";
			 			infobox = 0; 
						document.getElementById(imgid).src = "img/treemenu/identify_1.gif";
						}
}		

function setHTML(response) { 
   OpenLayers.Util.getElement('nodeList').innerHTML = response.responseText;
}

---------
but now i get:

coord is not defined
[Break on this error] coords: coords.lon+","+coord.lat,
