Newbie having problems with print

disturbedspike · May 9, 2006

Ok, I'm newbie and am having some problems! At first I was having problems getting page to view correctly, updated the php version, all is good there.
I don't know if I have fudged up my code, but when I enter values on the page and click the button, there is nothing that is being printed back to me....

<HTML>
<head>
<title>Zellers Carpeting Cost Estimate</title>
</head>

<?php

$bValid = true;
$strMessage = "There is a problem with the following items: ";
//set vars if there is anything in the query string

if ((count($_GET) >0)) {
$width = $_GET['width'];
$length = $_GET['length'];
$carpet = $_GET['carpet'];
$padding = $_GET['padding'];

if ((!is_numeric($width)) || (!is_numeric($length))) {
$bValid = false;
$strMessage = "$strMessage Width and length must be a valid numbers...";
}
if ($carpet == "") {
$bValid = false;
$strMessage = "$strMessage Carpet must be selected...";
}
if ($padding == "") {
$bValid = false;
$strMessage = "$strMessage Padding must be selected...";
}

if (isset($_GET['install']) == false) {
$bValid = false;
$strMessage = "$strMessage You must choose Installation or not";
$install = "";
}
else {
$install = $_GET['install'];
}

}
// if validation fails, set the vars to empty strings, display error message(s)

else {
$width = "";
$length = "";
$carpet = "";
$padding = "";
$install = "";

}
if ((count($_GET)==0)||($bValid ==false)){

if ($bValid==false){
print ("<div class='errorMsg'>$strMessage</div>");
}
}
?>

<body>
<div id="banner">

of the cost of carpeting your room</div>
