Pass variable in return URL

[carrzkiss]

Hello, All.

OK, I need to add a tempID to the Button.
And once the person completes the order and is sent back to my sites ThankYou page.
I need that tempID to be in the URL, so I can then have the person create an account on the site.
This way if the person is logged into the site, their order will be placed in their account.
And if it is a new user, the tempID will be stored in a cookie and then they can create an account once the order is completed.

I used to be able to do this years ago, but it seems that PayPal has changed this, at least that is what I am seeing from others that are trying this.
Any ideas on this one?

Thanks, Carrzkiss

I am reading through the 

HTML Variables for PayPal Payments Standard

And it states this, for
Item_Number =
Pass-through variable for you to track product or service purchased or the contribution made.
The value you specify is passed back to you upon payment completion.

However, the only thing that is being passed back is this.
&Payment=Successful&amt=43.94&cc=USD&st=Completed&tx=#######

It does not pass anything else back.
