Thank you so much for replying. It's good to know that someone is listening!

I called paypal, and they said it's because that because I'd used the same html code for each button, (I just added another "input" line for each product with a special "item_name" to differentiate...but it worked for months that way! They r calling me back...Told them I needed them at least to let me use it until I can get another shopping cart which allows more automation.
Regarding WAMP, at one point that was working too (then I changed from trial version CS4 where I must have had the settings correct to DW CS3 and it won't work). before that, it seemed that my files were automatically being saved to the www folder as well as my site root folder. (I think, anyway). Do you mean I have to save everything in the www folder as well as site root? Or should my site root be in www?
I figured the problem is in my DW site settings as it worked before.
