Please post the finished code returned by your script to the user...specifically show the HTML that builds the select dropdown.
My guess that you need to add space:
option value"<?php echo $row3["club_id"]; ?>"></
and make it option value "<?php echo $row3["club_id"]; ?>"></
I think if you look at the returned code, it will say
<option value"xxx">
and PHP returns the value, not the value" of the select. If there is no value (and if I'm right about this typo, there isn't), then PHP returns the Label of the select...which is what you are GETting.
