Hi, I am new to that job..I want to write a script that creates a time limit when user signs in. (Just for practising,itsnt useable )
I wrote something like that , but it doesnt work ;



function OnEvent_Signin(Mail)
{
        var time;
        var Message = "Your time has started!";
        MsgPlus.DisplayToast("Notice",Message);
        MsgPlus.AddTimer(time,600)       
}

function    OnEvent_Timer(time)
{
        var Message = "Your time is over..Signing out!";
        MsgPlus.DisplayToast("",Message);
Signout();
}



I know i am just a starter,so there can be silly codes up there ...

Thanks for your help.
