Well, don't use () in the name, but []...

A little hint for debugging POSTs: echo file_get_contents('php://input')
will give you the raw input.

Example:
------------------
POST:
<?php
var_dump($_POST);
?>
INPUT:
<?php
echo file_get_contents('php://input');
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<select name="check()" multiple>
<option>option 1</option>
<option>option 2</option>
<option>option 3</option>
<option>option 4</option>
<option>option 5</option>
<option>option 6</option>
</select>
<select name="check2[]" multiple>
<option>option q</option>
<option>option e</option>
<option>option r</option>
<option>option t</option>
<option>option y</option>
<option>option u</option>
</select>
<input type="submit">
</form>
