[Justa Lol]

<?php
if (isset($_POST['submit']))
{
if (empty($_POST['emne']))
{
echo "Du skal indtaste et emne<br><br>";
}
elseif (empty($_POST['email']))
{
echo "Du skal indtaste din e-mail<br><br>";
}
elseif (empty($_POST['mobilnr']))
{
echo "Du skal indtaste dit telefon nummer<br><br>";
}
elseif (empty($_POST['besked']))
{
echo "Du skal indtaste en besked<br><br>";
}
else
{
$modtager = ""; // removed mail from post
$emne = $_POST['emne'];
$besked = "Hej, Du har modtaget en mail fra en gæst: \n
Email: " . $_POST['email']. "\n
Telefon Nummer: " . $_POST['mobilnr']. "\n
Besked: " .
"\n" . "\n" . $_POST['besked'];

mail($modtager, $emne, $besked);
echo "Beskeden er nu send!<br><br>";
}
}
?>

<form name="email" action="?a=booking" method="POST">
<table>
<tr>
<td>Emne:
<br>&nbsp;&nbsp;<input type="text" name="emne" size="30"></td>
</tr>
<tr>
<td>E-mail:
<br>&nbsp;&nbsp;<input type="text" name="email" size="30"></td>
</tr>
<tr>
<td>Telefon Nummer:
<br>&nbsp;&nbsp;<input type="text" name="mobilnr" size="30"></td>
</tr>
<tr>
<td>Besked: <br>&nbsp;&nbsp;<textarea name="besked" rows="10" cols="30"></textarea></td>
</tr>
<tr>
<td><br>&nbsp;&nbsp;<input type="submit" name="submit" value="Send Besked"></td>
</tr>
</table>
</form>

i can't figure out whats wrong with this code, it used to work and now it doesn't, i haven't changed it a bit since i made it...

edit: i figured out the problem, i corrected the code so if anyone needs it...
