Message box wont pop up

[Ni3ls]

Hi all,
I made a kick function and when u are kicked a message box should pop up.

       
        self setClientCvar("com_errorTitle", "KICKED");
	self setClientCvar("com_errorMessage", "You are kicked by: " +admin +"\n" + "^7Reason: "+reden);
	wait 1;
 	self setClientCvar ("clientcmd", "disconnect");

I disconnect but no message. There is also no error in the code
