   	   {  
   		  var select;     		   
   		   var ft = 
			'from=' + starts + '&to=' + ends; 
   		
		$.ajax({
			 url:'lft.php',					
			 type:'GET',
			 asynch: false,
		     data: ft, 
			  success: function(data)	
			  {		   							  
					select =  data;    							
					  console.log(select);	
					}  
			});
