BR to display alert on case

[Jason116]

Can some please help me write a BR so that an alert (pop up message) is displayed when ever an update is made to a case from a specific contact, I hav tried the following but it's not working?

(function executeRule(current, previous /*null when async*/) {

    // Check if the contact is Test

    if (current.contact == 'Test') {

        // Display pop-up message

        var alertMessage = 'A new update has been made to the case.';

        var script = "alert('" + alertMessage + "');";

        gs.getSession().getClient().runScript(script);

    }

})(current, previous);

@Jason116 alert is a client side script function and a business rule is a server side script. You will not be able to call a client side method from server side. Instead you need to use gs.addInfoMessage() or gs.addErrorMessage() to show message to the user.

Here is the updated script.

(function executeRule(current, previous /*null when async*/) {
    // Check if the contact is Test
    if (current.contact == 'Test') {
        // Display pop-up message
        var alertMessage = 'A new update has been made to the case.';
        gs.addInfoMessage(alertMessage);
    }
})(current, previous);

Thanks, i need this to display as an alert though i.e. i need a window to pop up with the message and the user to click 'ok ' to acknowledge it, how can i do this? if this needs to be another script i.e client script how would this look?
