The document Building a Simple PayPal Buy Now Feature describes how to create a PayPal "Buy Now" (or "Donate") Module that can be added to a Page. In addition to "Buy Now" and "Donate", Paypal offers another payment method called "Subscribe". The HTML that PayPal generates for "Subscribe" is similar to that of "Buy Now" and "Donate" but adds a table, and "on0" and "currency_code" input lines as shown below. Does anybody know how to incorporate this additional HTML into the referenced Module 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="ABCDEFGHIJKLM">
<table>
<tr><td><input type="hidden" name="on0" value="Donation Options">Donation Options</td></tr><tr><td><select name="os0">
<option value="Option 1">Option 1: $10.00 USD - monthly</option>
<option value="Option 2">Option 2: $15.00 USD - monthly</option>
<option value="Option 3">Option 3: $25.00 USD - monthly</option>
<option value="Option 4">Option 4: $50.00 USD - monthly</option>
<option value="Option 5">Option 5: $100.00 USD - monthly</option>
<option value="Option 6">Option 6: $250.00 USD - monthly</option>
<option value="Option 7">Option 7: $500.00 USD - monthly</option>
<option value="Option 8">Option 8: $1,000.00 USD - monthly</option>
</select> </td></tr>
</table>
<input type="hidden" name="currency_code" value="USD">

I did read the article. The Easy Developer Solution section of that article described how to create a PayPal Module (ascx) for the "Donate" or "Buy Now" form. I was able to create a "PayPal Donate" Module following those instructions. My problem is that the PayPal "Subscribe" form includes additional lines (the ones in bold in my original message) and I don't know how to include those lines in the Module code.

I have successfully created an .ascx module for a "Subscribe" button (per Joe's directions), and it works as it should - up until PayPal returns to my site (I have my IPN return page set to "/Services/PayPalIPNHandler.aspx" on the PayPal site).  At this point, my website just "hangs," sitting there with a white screen, not doing anything discernible.  I looked at the source code for the IPN handler page, and cannot figure out what is going on.  What is PayPal sending/not sending that the IPN handler needs?

The process works perfectly for any cart items, just not for this Subscribe module.

Any help would be appreciated.
