PayPal IPN Woes

[hdog]

I have been trying to get perform a validation on my page which receives a URL string from PayPal IPN and then reposts the string to PayPal with an additional variable appended to the end of the string. I am supposed to get a "Verified" response back but instead keep getting back a "Invalid" response. Can anyone help?

Here is the string I am posting back to PayPal...

Here is my code (I'm using linked text for now but can see the variables being passed into my asp form):

<A HREF="

https://www.sandbox.paypal.com/cgi-bin/webscr?<%=

Request.QueryString()+"&cmd=_notify-validate"%>">Related</A>

Is what you provided copied and pasted from your code? If so, you have a misplaced semicolon between the first < and the %. I see the semicolon in the URL you post, too, right before cm=.

If you're using VBScript for your ASP, the plus sign should be a & as well, though what you have is correct for JScript ASP.

I'm not sure where the mystery ; came from but it is not in my URL string that I posted. Looks like it was a typo. Here is what paypal is posting to my asp page...

And here is what I'm posting back to paypals server...

Neither have the ";" you spotted. Any other thoughts?

There's that darn ";" again! It must be getting changed with this text box.

Let me try putting it in without the http....
