This the script that is falling over..... It calculates everything correct until the amount reaches £1,000, and then it falls over and reads only the 1 before the comma, and then outputs the price to be paid as £1.18 (£1 + the taxrate (0.175 rounded up))
<? echo "<p>Order Processed at "; echo date("H:i, jS F"); echo "<br>"; echo "<p>You ordered:"; echo "<br>"; echo $tyreqty." Tyres<br>"; echo $oilqty." Bottles of Oil<br>"; echo $sparkqty." Spark Plugs"; $totalqty = 0; $totalamount = 0.00; define("TYREPRICE", 100); define("OILPRICE", 10); define("SPARKPRICE", 5); $totalqty = $tyreqty + $oilqty + $sparkqty; $totalamount = $tyreqty * TYREPRICE + $oilqty * OILPRICE + $sparkqty * SPARKPRICE; $totalamount = number_format($totalamount, 2); echo "<br>\n"; echo "Items Ordered: ".$totalqty."<br>\n"; echo "Subtotal: £".$totalamount."<br>\n"; $taxrate = 0.175; //local tax rate in UK is 17.5% $totalamount = $totalamount * (1 + $taxrate); $totalamount = number_format($totalamount, 2); echo "Total Including Tax: £".$totalamount."<br>\n"; ?>

Here's your problem:
$totalamount = number_format($totalamount, 2);
That creates a string with a comma in it. When you try to read it as a number again, the comma screws it up. Wait to do the number_format until you output like this:
echo "Subtotal: £".number_format($totalamount, 2)."<br>\n"; ... echo "Total Including Tax: £".number_format($totalamount, 2)."<br>\n";
In other words, instead of assigning the number formatted string back to $totalamount, format it only on output.
