URGENT Paypal button (Haiti)

[Rapz]

I'm having members donate money for Haiti. they can 'buy' a colored username.

the code doesn't work the error I get is:

You did not select any posts to which the action you picked can be applied.

the code:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="11349287">
<table>
<tr><td><input type="hidden" name="on0" value="Options">Options</td></tr><tr><td><select name="os0">

SPACE BECAUSE ELSE THE BUTTON WILL SHOW UP

<option value="Colored">Colored $2,50</option>
<option value="Colored &amp; Bold">Colored &amp; Bold $5,00</option>
</select> </td></tr>
</table>
<input type="hidden" name="currency_code" value="USD">
