ServerCmd doesn't work....

I have defined a function in my common/server/commands.cs just like this

function serverCmdLogin (%client, %username, %password) {
	echo ("\n++++++++++++++ Entering ServerCmdLOGIN ++++++++++++++++++++");
	
	%query = "SELECT password FROM tge WHERE username = '" @ %username @ "'" ;
	%result = $db.Execute (%query);
	if (!%result) return 0;
	if (%result.password !$= %password) return 0;
	return 1;
}

then i called it from control/client/misc/loginscreen.cs just like this :

echo ("\n++++++++++++++ Before Calling ServerCmdLOGIN ++++++++++++++++++++");
commandToServer ('Login', $pref::player::name, $client::password);

now why the heck, the echo ("\n++++++++++++++ Entering ServerCmdLOGIN ++++++++++++++++++++"); doesn't appear in my console.log, and the specified function is not called at all......... something is definetly very wrong with this... please help me guys..
