Query not working !!!

[Sorrow]

Ok here's the deal I have this code [code]<?php

$Valeur = $_Post["Username"];

$con = mysql_connect("localhost", "db_user", "db_pass") or die(mysql_error());

mysql_select_db("db_name", $con);

$result = mysql_query("SELECT * FROM Usagers WHERE Username =  '". $Valeur . "'" );[/code]

When I replace this part ( '". $Valeur . "'" ) by the value of a username in my database it is working all the infos i am asking i have them but when i go from the login page and try to send the value to : $_Post["Username"] their is nothing that shows up. And yes all the fields are name the same.

$_Post should be $_POST (case sensitive)

What is you forms submit method? This is defined in the form tag via the method attribute.

Also little confused about your last post. What do you mean [b]already checked this[/b].

$Valeur = $_Post["Username"]; should be $Valeur = $_POST["Username"];
