This error message "Missing argument 2 for validateInput()"
I created a function safe variable (preg_replace) so I can keep my form a little more secured. The function validateinput has the "safe" but when I process my contact form, I get this error. The form submits the info to my email but I don't know why i'm getting that error.
Warning: Missing argument 2 for validateInput(), called in D:\Hosting\9777689\html\process.php on line 122 and defined in D:\Hosting\9777689\html\process.php on line 108

$retval = trim($data);
$retval = stripslashes($retval);

$Comments = validateInput(safe($_POST['comments'], "Comments"));
$Company = validateInput(safe($_POST['company'], "Company"));
$Position = validateInput(safe($_POST['position'], "Position"));
$Phone = safe($_POST['phone']);
if ($errorCount>0){
echo "Please re-enter the information below.<br />\n";
redisplayForm($Name, $Email, $Phone, $Company, $Position, $Comments);
