I've received a patch of HTML code from PayPal:

<form target="paypal" 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="XLKHEXEGWSXYL">

<table>

<tr><td><input type="hidden" name="on0" value="Color">Color</td></tr><tr><td><select name="os0">

<option value="Option 1">Option 1 $239.00 USD</option>

<option value="Option 2">Option 2 $239.00 USD</option>

<option value="Option 3">Option 3 $239.00 USD</option>

</select> </td></tr>

</table>

<input type="hidden" name="currency_code" value="USD">

<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_cart_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">

<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">

</form>

I do not know where to paste it so PayPal can process a sale.  Can someone please help me or point me to an accurate tutorial?   Thank you.
