Thanks Martin!! That really helped out a lot. And thanks to all who tried to
help me. I appreciate it!
I have one other question that is really not so much important as it is
annoying, but I can't figure it out myself.
I'm practicing with sessions. What I'm making..if you couldn't tell by the
array output from before...is a test shopping cart. Now the annoyance is
that when I click the checkout link it's just supposed to destroy the
session and reset everything to 0 including the shopping cart. And also if
an item is clicked, that item gets deleted. With both choices when I click
once the session does get destroyed, but everything stays on the page until
I refresh the page. I want the info to get reset when I click the link.
Here's the delete and checkout code...remember they both do actually work,
just not as I want. Any suggestions on how to make it refresh on a click
only?
/ DELETE SHOPPING CART ITEMS
function chout(){
session_destroy();
$mycart = array();
$cart_items = 0;
echo "<p>Thank you for shopping!</p>";
}
if ($action == delnow)
{
unset($mycart[$itemid]);
}
// END DELETE SHOPPING CART ITEMS
if ($action == checkout)
{
chout();
}

here's the revised loop....
$cat_cnt = count($catalog);
while (list($key,$value) = each($mycart))
{
for ($j = 0; $j < $cat_cnt; $j++)
if ($value == $catalog[$j]["itemcd"])
{
echo $catalog[$j]["unitprice"];
break;
}
}

Ah! $catalog is a 2D array - any your if statement is expecting a 1D
array...

Array ( [0] => gerainiums [1] => roses [2] => roses [3] => roses [4] =>
roses [5] => roses )

Your output is different from the last print_r that Tom had me do. I wonder
why that is

Hi
Then I guess you will have to add some debug code
try this before the while loop and make sure your if ($value ==
$catalog["itemcd"]) will produce a match (and you do need the quotes really
:)
echo "<pre>".print_r($catalogue)."<br>".print_r($mycart)."</pre>";
