Hip Hooray for Help Services That Work!

So after my last problem with the 'view cart' button I emailed PayPal and they got back to me with the answer - and now the problem is fixed and my button works!!

And I thought I'd post the answer here in case others have a similar problem or may understand what it is about:

"If you examine the source code of the PayPal payment buttons, check to see if the variables have numbers appended to them (e.g. 'cmd2', 'business2', 'item_name2', 'submit2', etc.). This is called enumeration and is probably caused by your web editor. Depending on your settings, some editors (notably Dreamweaver and FrontPage 2003) will automatically enumerate form variables in your HTML code.
Since our server does not recognize these modified variables, it will cause the buttons to not function correctly. This is why your buttons are going to the PayPal home page instead of a PayPal payment page. You will need to revise your HTML code and remove the numeral after each variable.
You can also disable Dreamweaver from enumerating your variables by following these steps:
1. In Dreamweaver, click 'Edit'
2. Click 'Preferences'
3. Under 'General', deselect 'Rename Form Items When Pasting' (for Dreamweaver MX, this option is located under 'Code Rewriting')
You can also prevent FrontPage 2003 from enumerating your variables by following these steps:
1. In FrontPage 2003, go to the top and click on 'Tools'
2. Click 'Page Options'
3. Select the 'General' tab, if not already selected
4. Clear the checkbox next to 'Make ID Unique on Paste'
5. Click the 'OK' button to save your changes
If you are not using Dreamweaver or FrontPage 2003, you will need to consult your editor's help files to learn how to disable this setting or you can manually remove the added numbers from the variable names in the HTML source code."
