            var bot = new OpenLayers.Control.Button({
    				displayClass: 'olIkonaUdalj', 
    				
    				eventListeners: {
				  	'activate': klikLivo,
				  	'deactivate': brisMarkera}, 
				  	type: 2
					});
					
				
					var kontr = new OpenLayers.Control.Panel
({
					 div: document.getElementById("bp"),
				    //defaultControl: bot
				  	});  
				kontr.addControls([bot]); 	
            map.addControl(kontr);	 
			            	 
            	 
          
            				
function klikLivo(event) {       		
var crta = new OpenLayers.Control.Measure(OpenLayers.Handler.Path, {persist: 
true, immediate: true});
            
                crta.events.on({
                    "measure": handleMeasurements,
                    "measurepartial": handleMeasurements
                });
                map.addControl(crta);
                crta.activate();

            var element = document.getElementById('au');
            var out = "";
            if(order == 1) {
                out += "measure: " + measure.toFixed(3) + " " + units;
