Php function and button

[mikerh9]

My code contains the php code:
<?php if ($action =="show") {
showForm();
Than it calls the showForm() function,

The button is given below, when I click on the button nothing happens or gives me an error message.

<form action="show">
<table cellSpacing="0" cellPadding="4" bgColor="#930000" border="0">
<tr><td><input type="hidden" value="send" name="action">
<input type="submit" name="submit" value="Apply" border="0">
</tr></td>
</table> </form></center>

What I'm doing wrong?

Thanks

The form action should point to the script that processes the form.
