Judy:
Is it possible that the following is what is needed to solve his problem:

1. Log onto your PayPal account
2. Click onto Merchant Services at the TOP
3. Midway down the page on the right hand side is a choice to "Buy Now Buttons" - you enter the information for your item there
4. THe information asked for is price, ID number for your info only, and auction number if necessary, shipping, and total amount due with sale and shipping
5. Click OK
6. PayPal generates UNIQUE code that only works for that one auction or sale.
6. Copy and past the code into your page and a PAYPA button will show up.
7. Customer clicks on it and is taken to your invoice page they enter in their info and the invoice is filled in with sale price, tax if applicable, shipping, and total.

Hope this helps. However, I may be way off base with this suggestion. Just thought I'd try.
