How do I check to see if my buy now button works correctly?

This may seem like a dumb question, but I need to find out if my "buy now" button works correctly. This is my first product, and I want to make sure that payment process goes the way it's suppose to go.

After purchasing the product, it is suppose to take you to the download page. Paypal wont let me check myself. When I click on the "buy now" button I get this message.

"You are logging into the account of the seller for this purchase. Please change your login information and try again."

Can someone tell me how to do this.

Thanks

Make a product with $0.01 and ask some your friend to test it and if he want money again refund him lolzzz that was easy

 

Lol. you have to make a automatic script. Because after he paid, he should automatically go to download page.

If you dont know how to make a script, take my help. or just take any other friends help.

 

make an paypal sandbox account (developer.paypal.com)...use 1 of that account to excpt the paymnt n othr to pay...and u can test it

 

Thanks first time heard rep added to you both
