How to use PayPal's Sandbox mode to test payments

Okay here's my dilemma. I set up a paypal form with two items for purchase. The form looks good. Drop down menus for quantity and size of items to be purchased. I have the form where the customer has to fill out their name, email and address.

I have provided my email paypal to initiate this form to accept paypal purchases. But... I cannot find any where to 'TEST' this form, so I used this form myself and I am NOT taken to the paypal site to make a purchase. I do however receive a thank you notice and also receive in an email a confirmation of my order but NOT any PAYPAL purchase. Please HELP!

Thank you.

You need to enable Paypal's Sandbox Mode. 

Here's how: 

You may also need to sign-up for a PayPal Sandbox account by clicking on the following URL:  https://www.sandbox.paypal.com/

Then, use the email address to make the PayPal payments.

I hope this helps. Do get back to us should you have any further questions. Thank you.
