Wait, can I ask you one more question... I'll ask you anyways.
You said that you saw the @ on a site, which site exactly?

I'll tell you privately, if you tell me why you want to know. I didn't see it "on a site." I saw it in the code for a site I was working on. I have no desire to insult or embarrass anyone. I got stuck cleaning up the mess this guy made so he is not my favorite person and that's why I referred to it as sloppy code.

I just dug out one of those files at random and sure enough that "@" sign is on every single query. Here is a chunk of the code and in 15 lines he used it 3 times. I had never laid eyes on php before so had no reason to question what he did. This is how I learned the little I know about php - by cleaning up his code. It's a case of the blind leading the blind, I'm afraid.

$sql = "SELECT MAX(Cust_No) FROM $table_cus";
$result1 = @mysql_query($sql,$connection) or die("Couldn't execute $sql query.");
$Cust_Num = mysql_result($result1, 0, 0)+1;

// Get Order Number

$sql = "SELECT MAX(Order_No) FROM $table_ord";
$result2 = @mysql_query($sql,$connection) or die("Couldn't execute $sql query.");
$Order_Num = mysql_result($result2, 0, 0)+1;

// Count Activities in Cart

$sql = "SELECT COUNT(Cust_ID) FROM $table_car WHERE Cust_ID = '$Cust_ID'";
$result = @mysql_query($sql,$connection) or die("Couldn't execute $sql query.");
$Max_Item = mysql_result($result, 0, 0);

Ok, I was just wondering.
