code needs to be rewriten cleaner

[Nihilists]

Following is the script thats needs to be placed in a if statment.

      <input type="hidden" name="order" value="<?php echo $_POST['itemNum']; ?>----<?php if($shopDesc) {print"$shopDesc";} else {print"$line1";} ?>----<?php if(($color == "ColorAdd") || ($size == "SizeAdd") || ($style == "StyleAdd")) {
   echo "0.00";
} else {
   echo $price;
} ?>----2----1">

The if statement will be:

if($diffitemnum==blank) { above script }

If the $diffitemnum==anything else it will recreate the hidden field elsewhere which I could do it once this is completed.

Variables:
$diffitemnum = drop down menu
itemNum = input field
$shopDesc = input field
$line1 = input field
$color = drop down menu
$size = drop down menu
$style = drop down menu
$price = input field

There are two files auto.html thats passes the varialbles to the php script, automate.php

Thanks for any help in advance
