When I try to echo the values selected in my select boxes  ( $first and $last ) nothing shows up....

 

I'm wondering if my user created function isn't naming them like I'd like...

 


<html xmlns="http://www/w3c.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Catherine: TV Test</title>
<script type="text/javascript">
function load()
{
    var wH = window.innerHeight;
    var wW = window.innerWidth;
    document.getElementById('windowWidth').setAttribute('value',wW);
    document.getElementById('windowHeight').setAttribute('value',wH);
}
</script>
<style type="text/css">
    #main {
        position: relative;
        height: 100%;
margin-left: 20px;
margin-right: 20px;
    }
    table {
    position: relative;
    top: 20px;
    margin-left: auto;
    margin-right: auto;
    text-align: center;
    }

    
<?php
echo '#leftbar {
position: absolute;
top: 20px;
left: 0px;
width: 50%;
height: 600px;
background-color: rgb(0,0,255);
}';
?>
</style>
</head>
<body onload="load()">
<div id="main">
<?php
if (isset($_POST['submitted']))
{
    $bars = $_POST['stages'];
    $first = $_POST['first'];
    $last = $_POST['last'];
    echo "You entered $bars stage(s). ";
    echo "Your first color is $first. Your last color is $last.";
    //Gradient display code:
    // echo '<div id="leftbar"></div>';
   

} else
{
	/* The two following tags MUST included in a form that YOU design within
	 * this section of PHP code.
	 */
    // Function to create a uniquely named 20+ color select menu
    function Selectors ($a){
	echo '<select name="$a">';
	echo '<option value="127,255,212">Aquamarine</option>';
	echo '<option value="0,0,0">Black</option>';
	echo '<option value="0,0,255">Blue</option>';

to clear out some of the junk code...

 

    // Function to create a uniquely named 20+ color select menu
    function Selectors ($a){
	echo '<select name="$a">';
	echo '<option value="127,255,212">Aquamarine</option>';
	echo '<option value="0,0,0">Black</option>';
	echo '<option value="0,0,255">Blue</option>';
	echo '<option value="220,20,60">Crimson</option>';
	echo '<option value="0,255,255">Cyan</option>';
	echo '<option value="148,0,211">Dark Violet</option>';
	echo '<option value="255,20,147">Deep Pink</option>';
	echo '<option value="255,215,0">Gold</option>';
	echo '<option value="255,0,255">Magenta</option>';
	echo '<option value="25,25,112">Midnight Blue</option>';
	echo '<option value="255,165,0">Orange</option>';
	echo '<option value="128,0,128">Purple</option>';
	echo '<option value="255,0,0">Red</option>';
	echo '<option value="65,105,255">Royal Blue</option>';
	echo '<option value="192,192,192">Silver</option>';
	echo '<option value="135,206,235">Sky Blue</option>';
	echo '<option value="0,255,127">Spring Green</option>';
	echo '<option value="64,224,208">Turquoise</option>';	
	echo '<option value="238,130,238">Violet</option>';
	echo '<option value="255,255,0">Yellow</option>';	
	echo '</select>';
    }
    
    // Variables to use when calling the previous function
    $f = "first";
    $l = "last";
    
    //begin html form
    echo '<form action="tvtest.php" method="POST">';
        //Hidden input...
	echo '<input type="hidden" name="windowWidth" id="windowWidth" />';
	echo '<input type="hidden" name="windowHeight" id="windowHeight" />';
	// Input table
	echo '<table>';
	echo '<tr>';
	echo '<td><label>First Color:</lable></td>';
	echo '<td>';
	Selectors($f);
	echo '</td>';
	echo '</tr>';
	echo '<tr>';
	echo '<td><label>Second Color:</lable></td>';
	echo '<td>';
	Selectors($l);
	echo '</td>';
	echo '</tr>';
	echo '<tr>';
	echo '<td><label>Number of Stages: </label></td>';
	echo '<td><input type="text" name="stages" /></td>';
	echo '</tr>';
	echo '<tr>';
	echo '<td colspan="2">';
	echo '<input type="submit" name="submitted" value="Show Pattern" /></td>';
	echo '</tr>';
	echo '</table>';
	echo '</form>';
	//End html form

 

and then

 

if (isset($_POST['submitted']))
{
    $bars = $_POST['stages'];
    $first = $_POST['first'];
    $last = $_POST['last'];
    echo "You entered $bars stage(s). ";
    echo "Your first color is $first. Your last color is $last.";
