help with calculations

[capb]

Hello,
I am trying to create an order form which uses different prices based on quantity ordered. Here is what I have:

ELSEIF ($action==" Review Order "):
$totalquantity = ($quantity50001);
if ($quantity50001 <= 0) {
$total50001 = "0";
$quantity50001 = "0";
}

 	if ($totalquantity <= 0) {
	$thetotal = "0";
	$total50001 = "0";
	$quantity50001 = "0";
	}
 	if ($totalquantity > 0 < 11) {
	$total50001 = ($quantity50001 * 59.00);
	$thetotal = ($totalquantity * 59.00);
	}
 	if ($totalquantity > 10 < 26) {
	$total50001 = ($quantity50001 * 54.00);
	$thetotal = ($totalquantity * 54.00);
	}
 	if ($totalquantity > 25 < 51) {
	$total50001 = ($quantity50001 * 49.00);
	$thetotal = ($totalquantity * 49.00);
	}
 	if ($totalquantity > 50 < 101) {
	$total50001 = ($quantity50001 * 44.00);
	$thetotal = ($totalquantity * 44.00);
	}
 	if ($totalquantity > 100) {
	$total50001 = ($quantity50001 * 39.00);
	$thetotal = ($totalquantity * 39.00);
	}

?>

When I run the code, I get an error message at the first line. Can anyone tell me what I'm doing wrong?

Thanks

well you cant start a statement with elseif. is there any code before this line?

[leatherback]

And if there is code before it:

After the elseif you should have a { instead of a :

Sorry,
There is a lot of html code before it. As for the php script, the first lines are

<?php
exit;

I tried changing the : to { but it still didn't work.

I get this message when I load the page:

Parse error: parse error, unexpected '{', expecting ':' in /home/pmc/public_html/one-source_order.php on line 216

Thanks for your help.

Are you using the alternate syntax for if/elseif? If so, then you are mixing syntaxes, and that is bad anyhow...

Post about 10-20 lines before your elseif. It may be something in there. You may ned to give code going all the way back to your initial IF that this ELSEIF ties into. Lastly, do you have an ENDIF; for this alternate if/elseif syntax?

I got it. I forgot to use elseif instead of just if.
Thanks for everyone's help.
