when i choose few items from the list in the main page, it will open a new page which will display the no of item choosed and the particular colors. the problem is, when i hit the select button, it prompt "you had choose 0 color.." then there is error at my foreach function..

</head>

<body>
<table width="42%" border="1" align="center">
<form name="page1" action="displaycolour.php">
<tr>

Replace the <?php ... ?> block in the 2nd file with:


<?php
echo "You had selected ".count($_GET['selcolour'])." colours. They are :<ul>";
foreach ($_GET['selcolour'] as $col) {
echo "<li>$col</li>";
}
echo "</ul>";
?>
