Hi Abraham,
I think you didn't put the alert javascript function inside a script tag. Anyway, it's advisable to just return the error message and let KoolGrid shows it for you.

Hi there David.
The alert on this section:
		if($value>$xAmortizar){
			alert("La suma de las Amortizaciones no debe exeder los Anticipos");
			return null;
		}

is actualy a php functions that hanldes the string msg and pass it to a java script calling the alert..
.. the reason i wont let the validator to return the msg is that this is just a Warning validator not an on error stop inserting...
.. seems that ajaxs has somthing to do with this issue..
still traing to figre it out.
i can allways set a $_Session variable and catch it on OnConfirmInsert event to send the Warning alert.. but... you know.. i wannt to code preaty lol.

well this is my work arround..
my validator:
	function validaAmortizacion(&$value){
		$value = str_replace(",","",str_replace("$","",$value));
		$xAmortizar = $_SESSION[basename($_SERVER['PHP_SELF'])."txtxAmortizar"];
		if(isset($_SESSION["xAmortizarOnEdit"])){
			$xAmortizar=$_SESSION["xAmortizarOnEdit"];
		}		
		if($value>$xAmortizar){
			setcookie("alertAmortizacion", "1"); // this is the cookie that will trigger the alert on the js event handler.
	     }
		unset($GLOBALS[_SESSION]["xAmortizarOnEdit"]);
	        return null;//returns null causes this validator is just a warning validator..
	}

add the event handler function to the grid..
$grid->ClientSettings->ClientEvents["OnGridCommit"] = "Handle_OnGridCommit";

then in js Handle_OnGridCommit
	function Handle_OnGridCommit(sender,args){
		var alertAmortizacion = getCookie("alertAmortizacion");//get the cookie value;
		if(alertAmortizacion=="1"){
			clearCookie("alertAmortizacion");//clear the cookie so it dies.
			alert("La suma de las Amortizaciones no deberia exceder los anticipos!!");
		}
	}
