Displaying Image Based On Field Value

I am trying to display an image based on the value of a field. I am getting this error.

This works. But would a switch be better?

<?PHP  
If ($Rating == ".5") 
	{
	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/RedHalfHead.png>");
	}
elseif ($Rating == "1")
	{
	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red1Head.png>");
	}
elseif ($Rating == "1.5") 
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red1HalfHead.png>");
	}
elseif ($Rating == "2")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red2Heads.png>");
	}
elseif ($Rating == "2.5")
	{
 print ("<IMG SRC=http://www.menuhead.net/Images/Icons/Red2HalfHeads.png>");
	}
elseif ($Rating == "3")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red3Heads.png>");
	}
elseif ($Rating == "3.5")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red3HalfHeads.png>");
	}
elseif ($Rating == "4")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red4Heads.png>");
	}
elseif ($Rating == "4.5")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red4HalfHeads.png>");
	}
elseif ($Rating == "5")
	{
 	print ("<IMG SRC =http://www.menuhead.net/Images/Icons/Red5Heads.png>");
	}

Probably a switch would be better, but why not just have an array containing the strings?

You could set the index to the array with:
$idx=$rating/.5-1;
And go directly to the array to get the image.
