500 Internal Server Error for enquiry form

[joharm]

Hi everyone, I am not a PHP expert in any way but I do dabble a bit with enquiry forms.

 

One form, setup to simply email data from the form to an email address is giving me an Internal Server Error 500.

 

PHP Version 5.2.6. Client is using Fasthosts Windows Business hosting package, I assume IIS6.

 

I simply want to know whether this is coming from a script error my end, or from Fasthosts. I have trawled the internet all morning and tried out different sections of my code.

 

I believe it is coming from when the variables are picked up with $_POST - if they are empty (which they can be) I get the 500 error.

 

<?php
// Strip tags from the email

$firstname = trim(strip_tags($_POST['firstname']));
$lastname = trim(strip_tags($_POST['lastname']));

$purpose = trim(strip_tags($_POST['purpose']));
$employees = trim(strip_tags($_POST['employees']));

Any help at all would be appreciated!

Just in case anyone else has this problem:

 

The problem is not an Internal Server Error. For some reason ANY syntax errors or any empty variables cause this error at Fasthosts. Check and check again for syntax errors!!!
