I added a figure in below:

I am awaiting for an affirmative response from you. How can I check it?

Answer 1

You said that you are using sandbox environment for testing paypal transactions, but I can see that you webpage it's on paypal. Therefore any sandbox accounts won't work on the sandbox environment.

You need two accounts created in sandbox: one for business ( type of account needs to be business ) one for purchases ( type of account needs to be personal )

Also, make sure that any form action attribute points to sanbox.paypal.com not paypal.com

Hope that helps

EDIT: you can make purchases using the personal account
