Parse error: syntax error, unexpected T_STRING in PHP

hello,

i'm new in PHP coding. Please help me in solving this error.

Parse error: syntax error, unexpected T_STRING in C:\wamp\www\test\testdate.php on line 49

Line 49 is :Valid Oxygen:$oxygenmin-$oxygenmax

I attach together the whole coding for my project:

<?php

require("phpmailer/class.phpmailer.php");

$db_connect=mysql_connect("localhost","root","");
if(!$db_connect)
 {
 	die("Could not connect:".mysql_error()); 
 
 }
mysql_select_db("mpob",$db_connect);

/****2)RETRIEVE DATA FROM VALID PARAMETER****/

$query1="SELECT oxygenmin,oxygenmax,carbondioxsidemin,carbondioxsidemax FROM validparameter";

$result=mysql_query($query1);
list($oxygenmin,$oxygenmax,$carbondioxsidemin,$carbondioxsidemax)=mysql_fetch_row($result);
	
/***RETRIEVE DATA FROM CURRENT PARAMETER****/

$query = "SELECT *FROM currentparameter WHERE oxygen<$oxygenmin OR oxygen >$oxygenmax OR carbondioxside <$carbondioxsidemin OR carbondioxside >$carbondioxsidemax";
//echo $query;
$result2=mysql_query($query);

list($oxygen,$carbondioxside)=mysql_fetch_row($result2);
