Fatal Error in PHP coding

[petermoses]

I am encountering an error with the following section of PHP and cannot see the reason. The error is being trapped with the line

Code:

$validator->validateTextOnlyNoSpaces($HTTP_POST_VARS['name'],'section name');

The error message is:
Fatal error: Call to a member function validateTextOnlyNoSpaces() on a non-object in C:\Program Files\xampp\htdocs\newsite2\cmsadmin\newSection.ph p on line 33

Now, this implies that the $HTTP_POST_VARS field of 'name' is not in existence and yet I have declared it clearly within the form at the bottom of the code. The submit is set correctly.

Anyone see what I am missing?

$sectionID = $HTTP_GET_VARS['id'];

// Validate the section ID, and if it's ok then delete the section
if ( $validator->validateNumber($sectionID,'Section ID') )
{
// The validator returned true, so go ahead and delete the section
$connector->query('DELETE FROM cmssections WHERE ID = '.$sectionID);
echo 'Section Deleted <br><br>';
}
else
{

echo "Couldn't delete. There was a problem with: ".$validator->listErrors();
