I created a Pay Now button with drop-down options but only the last option correctly connects with Paypal. For the other options, we get a message from Paypal saying "Things don't appear to be working at the moment. Please try again later."
How can I fix this?
Here is the code for the button :
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="UN4C2PZY77FKA">
<table>
<tr><td><input type="hidden" name="on0" value="REQUEST REQUIRED:">REQUEST REQUIRED:</td></tr><tr><td><select name="os0">
<option value="Proof of Métis Ancestry - Family with origins in Manitoba">Proof of Métis Ancestry - Family with origins in Manitoba $28.00 CAD</option>
<option value="Proof of Métis Ancestry - Family with origins outside Manitoba">Proof of Métis Ancestry - Family with origins outside Manitoba $78.00 CAD</option>
<option value="10-generation Book">10-generation Book $120.00 CAD</option>
<option value="12-generation Book">12-generation Book $165.00 CAD</option>
<option value="15-generation Book">15-generation Book $205.00 CAD</option>
</select> </td></tr>
</table>
<input type="hidden" name="currency_code" value="CAD">
