Binding keyboard keys to actions

I'm trying to make a trigger that binds a keyboard key to a certain action when the player enters a trigger and unbind it when he leaves.

My trigger is called "Treasure"

The function I am binding to the key 'h' is called "LogoAction".

Heres the DataBlock I have for the trigger:
--------------------------------------------------------
datablock TriggerData( Treasure )
{
tickPeriodMS = 100;
};


function Treasure::onEnterTrigger( %this, %trigger, %obj )
{
bindcmd( keyboard, h, LogoAction);
echo( "*******h bound to LogoAction******");
};

function Treasure::onLeaveTrigger( %this, %trigger, %obj )
{
unbind( keyboard, h);
echo( "******h unbound*****");
};
-------------------------------------------------------------

Here's my DataBlock for the LogoItem (containing the "LogoAction" funtion):
---------------------------------------------------------------------------------------
datablock ItemData(TorqueLogoItem)
{
category = "Items";
shapeFile = "~/data/shapes/3dtorquelogo/torque_logo.dts";
};

function LogoAction()
{
MessageBoxYesNo("You found it!!!",
"Would you like to restart?",
"loadMyMission();"
"quit();");
};
------------------------------------------------------------------
As you can see I want a "Yes No" box to pop up when the 'h' is pushed while in the trigger. It's not working. I keep getting script errors when it tried to load these two files. I'm brand new at this and I'm just going off of examples and tutorials and trying to mix and match stuff. If you see what is wrong, help is appreciated.
