Default dynamic drop down menus

I got this script off of plus2net.com (if you want the code its at http://www.plus2net.com/php_tutorial/dd3.zip) and it isn't working for me.

PHP Code:

///////// Getting the data from Mysql table for first list box//////////
$quer2=mysql_query("SELECT DISTINCT style_name,style FROM products WHERE logo='proto' order by style"); 
///////////// End of query for first list box////////////

/////// for second drop down list we will check if category is selected else we will display all the subcategory///// 
$cat=$HTTP_GET_VARS['cat']; // This line is added to take care if your global variable is off
if(isset($cat) and strlen($cat) > 0){
$quer=mysql_query("SELECT * FROM products where style=$cat AND logo='proto' AND stock > 0"); 
$quer=mysql_query("SELECT * FROM products where style=$cat AND logo='proto' AND stock > 0"); } 
////////// end of query for second subcategory drop down list box ///////////////////////////

/////// for Third drop down list we will check if sub category is selected else we will display all the subcategory3///// 
$cat3=$HTTP_GET_VARS['cat3']; // This line is added to take care if your global variable is off
if(isset($cat3) and strlen($cat3) > 0){
$quer3=mysql_query("SELECT * FROM products where size=$cat3 AND style=$cat AND logo='proto' "); 
$quer3=mysql_query("SELECT * FROM products where size=$cat3 AND style=$cat AND logo='proto' "); } 
////////// end of query for third subcategory drop down list box ///////////////////////////

echo "<form method=post name=f1 action=''>";
//////////        Starting of first drop downlist /////////
echo "<select id=\"menu1\" name='cat' onchange=\"reload(this.form)\"><option value=''>--Style--</option>";
$noticia2 mysql_fetch_array($quer2)) { 
$noticia2['style']==@$cat){echo "<option selected value='$noticia2[style]'>$noticia2[style_name]</option>"."<BR>";}
"<option value='$noticia2[style]'>$noticia2[style_name]</option>";}
//////////////////  This will end the first drop down list ///////////

//////////        Starting of second drop downlist /////////
echo "<select id=\"menu2\" name='subcat' onchange=\"reload3(this.form)\"><option value=''>--Size--</option>";
$noticia mysql_fetch_array($quer)) { 
$noticia['size']==@$cat3){echo "<option selected value='$noticia[size]'>$noticia[size]</option>"."<BR>";}
"<option value='$noticia[size]'>$noticia[size]</option>";}
//////////////////  This will end the second drop down list ///////////

//////////        Starting of third drop downlist ///////// 
echo "<select id=\"menu3\" name='subcat3' ><option value=''>--Quantity--</option>"
$noticia mysql_fetch_array($quer3)) { 
$stock      stripslashes$noticia['stock'] ); 
if (
$stock 5) { 
   for (
$i 1$i <= $stock$i++) { $number $i; } 
else { for (
$i 1$i <= 5$i++) { $number $i; } 
"<option value='$number'>$number</option>"

//////////////////  This will end the third drop down list /////////// 

echo "</form>"
I think this is the chunk with the issues (kinda vague, I know but I do what I can). sooo I keep getting this oh so lovely error that says "mysql_fetch_array(): supplied argument is not a valid MySQL result resource" which is slightly angering since that is just about the only part I didn't change. Any ideas? Thanks in advance.
