there must be an error

[Lionheart1981]

I am trying to get this code to work that someone else wrote. This code has worked in the past, and hasn't been altered. I can't figure out where the problem is happening.

//****getting tax information *******//

if($TaxExempt == "no"){
$get_tax = mysql_query("SELECT * FROM shippinginfo WHERE userid = '$userid'");

if(!$get_tax){ echo mysql_error."error";}

$check_tax= mysql_num_rows($get_tax);

if($check_tax){
	while($row = mysql_fetch_array($get_tax)){
	foreach( $row AS $key => $val){
		$$key = stripslashes($val);
	}
	session_register('SCity');
	session_register('SCounty');
	session_register('SState');
	}//end while	
}//end if
if($SState == "Oklahoma"){
	$get_city = mysql_query("SELECT * FROM tax_city WHERE city = '$SCity'");
	$check_city= mysql_num_rows($get_city);

	if($check_city){
		while($row = mysql_fetch_array($get_city)){
		foreach( $row AS $key => $val){
		$$key = stripslashes($val);
		}
		session_register('city_tax');
		}//end while
	}//end if

	$get_county = mysql_query("SELECT * FROM tax_county WHERE County = '$SCounty'");
	$check_county = mysql_num_rows($get_county);

	if($check_county){
		while($row = mysql_fetch_array($get_county)){
		foreach( $row AS $key => $val){
			$$key = stripslashes($val);
		}
		session_register('County_Tax');
		}//end while
	}//end if

	$Tax = $city_tax + $County_Tax;
	$Tax = $Tax * $TotalPriceArray;
	$Tax = round($Tax*100)/100;
	$TotalWithTax = $Tax + $TotalPriceArray + $ShippingPrice;
	//print("Tax is $Tax");
	$update_tax_info = mysql_query("UPDATE rates SET Tax = '$Tax' WHERE Invoice = '$Invoice' ");
	if(!$update_tax_info){ echo mysql_error(); }
}
}

I attached an image of what the code looks like in dreamweaver, because it shows the code change from blue to black. that might help in finding the problem.
