Mail() not working

I am trying to use the mail() function to send an email in PHP.
I have altered the php.ini file to include the [mail function] with the parameter ;sendmail_path="(mypath)". The site is being hosted on a Linux server.

When I test the script I receive this error message:
Fatal error: Call to undefined function: ()
in quote_send.php on line 295

Here is the code I am using:
<?PHP
$mail_to = "me@myurl.com";
$mail_subject = "Quote Request";
$mail_body = "Here is a request for a quote:\n";
$mail_body .= "Name: " .$firstname . " " . $lastname . "\n";
$mail_body .= "Company Name: " .$company . "\n";
$mail_body .= "Email Address: " .$email . "\n";
$mail_body .= "Telephone Number: " .$telephone . "\n";
$mail_body .= "Job Title: " .$title . "\n";
$mail_body .= "Service Selected: " . $service . "\n";
$mail_body .= "Project Requirements: " . $requirements . "\n";
$mail_body .= "How you Heard about Us: " . $C . " " . $P . " " . $O . " " . $W . " " . $WS . " " . $S . " " . $OT . "\n";

/*this is line 295*/ if ($mail($mail_to, $mail_subject, $mail_body)) {
echo "mail sent successfully!";
} else {
echo "failed to send";
}
?>

The variables are sent via a form from the previous page.

What am I doing wrong??

Thanks.

if ($mail(....

When you place parenthesis after a variable, PHP will do the following:

It will expand the variable, and then try to execute a function that has the same name as the value of the variable.

For exampe, if you stored the text "is_array" in a variable named $foo, and then did this: $foo($myarray), it would execute the "is_array" function.

So, what you need to do is take that dollar sign off of the mail() function.

And thus endeth the sermon.

What a bonehead move! Thanks Dude.
