php script + not displaying webpage

Hi guys

Im in the process of designing a website for my company which does the following

1) Daily execution a perl script. The perl script's output is diverted to a .html file.

2) The .html file generated from 1) sets up a centralised webpage showing options as radio buttons (the radio buttons are given the same name to show grouping)

3) When clicking on one of the radio buttons, a .php script is executed which should show a webpage with a simple message in it.

The html code for the part with radio buttons is


<form action = "process.php" method="post">
<br/>
<input type="radio" name="group"  value = "member1"/>
<br/>
<input type="radio" name="group"  value = "member2"/>
<br/>
<input type="radio" name="group"  value = "member3"/>
</form>

And the .php script code (which is a separate .php file) is

<?php

print "<p>";
print "hello world";
print "</p>";

?>

I have executed this under the main html directory of my machine, so Im not sure what I could be doing wrong.

Ok an update on my situation

I read over HTML forms again and realised that in order for something to happen, data must be submitted

So I added an <input type='submit' value='Submit'> to my form and changed the method in <form> to get.

This enabled the server to reach the stage where process.php is being called, however unfortunately Im still not able to see the simple webpage generated by my .php script
