Hi all,
I'm an absolute newbie to PHP, but I need to send two values to a php-page and multiplay to calculate costs for an order.
Simplified, i have a form that sends number and price to calculate.php.
code:
<form name="form" method="post" action="calculate.php">
<table border="0" cellspacing="5" cellpadding="10">
<tr>
<td>tickets</td>
<td><select name="number">
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
<option value=5>5</option>
<option value=6>6</option>
<option value=7>7</option>
<option value=8>8</option>
<option value=9>9</option>
<option value=10>10</option>
</select></td>
</tr>

<tr>
<td> </td>
<td><input type="submit" name="button" id="button" value="calculate"></td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table><input name="price" type="hidden" value=6>
</form>

So the form sends the chosen number and the hidden value of 6 to calculate.php

Calculate php maltiplies both values. In code:

<html>
<head>Cost calculated</head>
<body>

<?php
$p=$_POST[price];
$n=$_POST[number];
$kosten = $p * $n;

echo $a "<br>"
echo $p "<br>"
echo $kosten "<br>"

?>

</body>
</html>

However, this results in a server-error.

Please, anybody, where do I go wrong?
