PHP Development Issue - the sequel

I have this code in place to define the quantity function (thx Brian:)...

<?php
$qty_string = "<input type=\"text\" size=\"2\" name=\"qty[]\" style=\"font-family: verdana; font-size: 8pt\" value=\"";

// Item 1
$qty = $_POST["qty"][0]; // Quantity after Update
$with_disc01 = round( (($price01*(round($discount01/100, 2)))-$price01), 2);
$ext_npl01 = ($price01*$qty);
$ext_inst01 = ($inst01*$qty);
$ext_maint01 = ($maint01*$qty);
$ext_usc01 = ($cost01*$qty);
// Item 2
$qty = $_POST["qty"][1]; // Quantity after Update
$with_disc02 = round( (($price02*(round($discount02/100, 2)))-$price02), 2);
$ext_npl02 = ($price02*$qty);
$ext_inst02 = ($inst02*$qty);
$ext_maint02 = ($maint02*$qty);
$ext_usc02 = ($cost02*$qty);
// There will be a total of 64 Items, this is just 2 of them
?>

So now I am working on creating totals and am looking for a way to use the existing quantities specified by the user, per item, to create them. I have tried a few different ways, but being a n00b I'm not having much luck. Here's an example of what I have tried...

<?php
$x_ext_npl = (($price01*$qty_string . $_POST["qty"][0])+($price02*$qty_string . $_POST["qty"][1])+($price03*$qty_string . $_POST["qty"][2]));
$x_ext_inst = (($inst01*$qty_string . $_POST["qty"][0])+($inst02*$qty_string . $_POST["qty"][1])+($inst03*$qty_string . $_POST["qty"][2]));
$x_ext_maint = (($maint01*$qty_string . $_POST["qty"][0])+($maint02*$qty_string . $_POST["qty"][1])+($maint03*$qty_string . $_POST["qty"][2]));
$x_ext_usc = (($cost01*$qty_string . $_POST["qty"][0])+($cost02*$qty_string . $_POST["qty"][1])+($cost03*$qty_string . $_POST["qty"][2]));
$x_ext_disc = (($with_disc01*$qty_string . $_POST["qty"][0])+($with_disc02*$qty_string . $_POST["qty"][1])+($with_disc03*$qty_string . $_POST["qty"][2]));
?>

Welll, it didn't work :) Anyone have any ideas? thanks for the help.

So the whole thing would look like this:

$x_ext_npl = (($price01*$_POST["qty"][0])+($price02*$_POST["qty"][1])+($price03*$_POST["qty"][2]));
$x_ext_npl = (($inst01*$_POST["qty"][0])+($inst02*$_POST["qty"][1])+($inst03*$_POST["qty"][2]));
$x_ext_npl = (($maint01*$_POST["qty"][0])+($maint02*$_POST["qty"][1])+($maint03*$_POST["qty"][2]));
$x_ext_npl = (($cost01*$_POST["qty"][0])+($cost02*$_POST["qty"][1])+($cost03*$_POST["qty"][2]));
$x_ext_npl = (($with_disc01*$_POST["qty"][0])+($with_disc02*$_POST["qty"][1])+($with_disc03*$_POST["qty"][2]));

That was it, thanks m8, I am still a bit confused by syntax at this point. I 'AM' learning though :)
