Creating ScoreCounter in Starter.fps

I am using the Getting Started PDF guide that ships with Torque to create what -- to me -- seems like it would be a very simple script. I want to create a ScoreCounter GUI, place objects on the map, and attach the ScoreItem dataBlock to it. I seem to have no problems doing that. I had to use some ingenuity, because I'm attempting to do it using Starter.fps as a template instead of Tutorial.base.

I made a GUI widget for ScoreCounter, and I placed my code snippets as follow:


// I put this in at the bottom of starter.fps\server\scripts\crossbow.cs:

datablock ItemData(ScoreItem)
{
// Mission editor category
category = "ScoreItem";

// Hook into Item Weapon class hierarchy.
className = "ScoreItem";

// Basic Item properties
shapeFile = "~/data/shapes/coins/coin.dts";
mass = 1;
elasticity = 0.2;
friction = 0.6;
emap = true;

// Dynamic properties defined by the scripts
pickUpName = "a coin";
}

function ScoreItem::onCollision(%this, %obj, %col)
{
if(%col.getClassName() $= "Player")
{
%client = %col.client;
%client.score++;
commandToClient(%client, 'SetScoreCounter', %client.score);
%obj.delete();
%coinCount = coins.getCount();
if(%coinCount > 0)
return;
// otherwise display victory screen
commandToClient(%client, 'ShowVictory', %client.score);
}
}


// Then I created a new script file called starter.fps\client\scripts\clientMsg.cs and I coded this in it:

function clientCmdSetScoreCounter(%score)
{
ScoreCounter.setText("Score:" SPC %score);
}
function clientCmdShowVictory(%score)
{
MessageBoxYesNo("You Win!",
"Would you like to restart the game ?",
"loadMyMission();",
"quit();");
}


// Then I opened starter.fps\client\init.cs and where there are all the client includes I called:

exec("./client/clientMsg.cs");


I double checked all my code, I deleted old cs.dso files, and then I launched the game mission, opened the editor, placed my coin objects around my map, and made sure they all share the ScoreItem dataBlock and are collidable. I also put them into a single SimGroup called coins. My character on-screen froze at that point, so I saved the mission, exited and then relaunched it.

My character can move around again, and I can find all the coins. Unfortunately, whenever I walk over a coin I just go right through it and nothing happens. I also noticed that I can't look around with the mouse anymore, although I can still right-click + Tab key to switch to 3rd person. Something serious must have gone wrong.

I'm in serious straits here! Can someone help me? I just need the player character to be able to pick up objects and have them add to his overall score. If there's an easier way to do it, please let me know!
