HELP PLEASE

Getting MANY Errors!!! Here they are! BCE0022: Cannot convert ‘int’ to ‘System.Type’. The type ‘UnityEngine.Rect’ does not have a visible constructor that matches the argument list ‘(float, System.Type, int, int)’. BCE0051: Operator ‘-’ cannot be used with a left hand side of type ‘System.Type’ and a right hand side of type ‘int’.BCE0051: Operator ‘+’ cannot be used with a left hand side of type ‘System.Type’ and a right hand side of type ‘int’.
Here is my code.

#pragma strict

var RedPlayer : GameObject;
var BluePlayer : GameObject;

var CurTeam : String = "";

var SpawnPointRed : GameObject;
var SpawnPointBlue : GameObject;

var CenterW : float;
var CenterH = float;

function Start ()
{
	CurTeam = "";
	CenterW = Screen.width / 2 - 150;
	CenterH = Screen.height / 2 - 80;
}
function OnGUI () 
{
	GUI.Box(Rect(CenterW, CenterH, 300, 160), "Select a Team");
	if(CurTeam == "")
	{	
		if(GUI.Button(Rect(CenterW + 5, CenterH - 20, 290, 65),"Red Team"))
	{
		
	}
	if(GUI.Button(Rect(CenterW + 5, CenterH + 120, 290, 65),"Blue Team"))
	{
		
	}
	}
	else
	{
		if(GUI.Button(Rect(CenterW + 5, CenterH + 20, 290, 130),"Respawn"))	
		{
		
		}
		
		}

}

Instead of:

var CenterH = float;

you need:

var CenterH : float;
