Donate button in .xhtml

[Dura Hurtado]

Hi, I am trying to set a paypal donate button in my app , but the code paypal give me is this way:

<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="EY7B7SPF95ZH8">
            <input type="image" src="https://www.paypalobjects.com/en_US/ES/i/btn/btn_donateCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
            <img alt="" border="0" src="https://www.paypalobjects.com/es_ES/i/scr/pixel.gif" width="1" height="1">

        </form>[

Then when I in it in a. xhtml page it doesn´t reconigze the form tag.

¿Anyone know what way could I in it?

Thanks in advence.
