Php ma function ne test pas les valeurs

Bonjour,

Il y 'a un autre probleme qui m'embette, j'ai lempression que ma function create_entry que voici:

function create_entry($name,$location,$email,$url,$comments){
$errmsg = "";
if(empty($name)){
$errmsg .= "<li>you have to put in a name!n";
}
if (empty($email)){
$errmsg .="<li>insert an email pleasen";
}
else {
$query = "select * from guestbook where email = '$email'";
$result = safe_query($query);
if(mysql_num_rows($result) > 0) {
$errmsg .="<li>this email has already sign this guestbook.n";
}
}
if (empty($errmsg)){
$query = "insert into guestbook"
."(name,location,email,url,comments) values "
."('$name','$location','$email','$url','$comments')";
$result = mysql_query($query);

?>
<h2>Thanks!!</h2>
<h2><a href="view.php">View Arly's Guest Book!!!</a></h2>
<?php

}
else{
echo "operation failedn";
}

}
?>

quand j'utilise $errmsg="<li>you have.......n" et if(empty($errmsg)){.....

une fois que les valeures sont submit... via le code sign.php, n'execute pas les operations de verification si le
$name a bien etait introduite ou si le $email existe deja il sort directement et viens a else pour m'aficher operation failed.
aucune errore ne m'est affiche.

voici sign.php
<?php
include "connection.php";
include ("usefulfunc.php");
$page_title = "Sign My Guest Book!!";
include "start_pag.php";

if(!empty($_POST['test'])){
$errmsg = create_entry($_POST['name'], $_POST['location'], $_POST['email'] , $_POST['url'] , $_POST['comments']);
if (empty($errmsg))
{
include "end_pag.php";
exit;
}
}
?>

<form method=POST>
<table>
<?php

print_input_fields("name","location","email","url");
?>
<tr>
<td valign=top align=rigth><b>Comments:</b></td>
<td valign=top align=left><textarea name=comments cols=40 rows=4></textarea></td>
</tr>

</table>
<input type=submit name=submit value="Sign!">
<input type=reset name=reset value="Start Over">
<input type='hidden' name='test' value="ok" />
</form>


Merci d'avance pour l'aide
