WHERE clause won't work with AND

[bump909]

Why won't MySQL return any values when I put an AND operator as part of the WHERE clause?
here is my code (the 1st one works):

$query_packaging = "SELECT * FROM packaging WHERE quantity = '$q'";
$result_packaging = mysql_query($query_packaging);
$row_packaging = mysql_fetch_array($result_packaging, MYSQL_ASSOC);

$query_packaging_desc = "SELECT quoteDesc FROM packaging_desc WHERE (formCode = '$SESSION[packaging]') AND (formCode = '$SESSION[overwrapping]')";
$result_packaging_desc = mysql_query($query_packaging_desc);
$row_packaging_desc = mysql_fetch_array($result_packaging_desc, MYSQL_BOTH);

I may be missing something blindingly obvious here, so please forgive me.

$query_packaging_desc = "SELECT quoteDesc FROM packaging_desc WHERE (formCode = '$_SESSION[packaging]') AND (formCode = '$_SESSION[overwrapping]')"; 

formCode and be
AND $SESSION[packaging]
AND $SESSION[overwrapping]

it can hold only ONE value per record at a time. Use OR instead.

Coding can be better too, use

$query_packaging_desc = "SELECT quoteDesc FROM packaging_desc WHERE (formCode = '" . $_SESSION[packaging]. " ') OR (formCode = '" . $_SESSION[overwrapping] . "')";

Ahh i see, you can store values from various columns into the array but not various rows from one column.
