CFSCRIPT not receiving variable

I have written a small script just to learn how, and I can't get this to work. The validation works fine, and the initial display is fine, but when you click on the image, I get a pop-up window that tells me "Player" is undefined in my script. I suppose I'm missing some small syntax that is causing the variable to not be passed into the function, but I've been through the documentation and haven't been able to find it. Maybe another set of eyes will. Here's my entire page:

<CFSET Player = &quot;Red&quot;>
<CFSET CurrentImage = &quot;GreenSquare.gif&quot;>

<!--- This is the script that actually performs the image swap. --->
<CFSCRIPT>
function SwapImage(Player)
	{
	if(Player EQ &quot;Red&quot;)
    	CurrentImage=&quot;RedCircle.gif&quot;;
  	else
    	CurrentImage=&quot;WhiteCircle.gif&quot;;
	return CurrentImage;
	}
</CFSCRIPT>

OK, here's the next version. I still get the pop-up window, only now it's telling me 'Red' is undefined. In addition, I don't get any output from the WriteOutputs in my script, so maybe it's not even getting that far. I'm getting a little frustrated with this, because I can't seem to get even a very simple script to work. ARRRGHHH!!! :-(

Just for additional FYI, the following script works as a stand-alone.
Code: 
<CFSCRIPT>
 	Color=&quot;Red&quot;;
	Player=&quot;Red&quot;;
	WriteOutput(Color);
	WriteOutput(Player);
	if(Player EQ Color)
    	CurrentImage=&quot;RedCircle.gif&quot;;
  	else
    	CurrentImage=&quot;WhiteCircle.gif&quot;;
	WriteOutput(CurrentImage);
</CFSCRIPT>
