Hi, I summarized what we have discussed so far. 
Please confirm or correct it.

============================================================
A contest owner can create as many contests as he wants.
A contest consists of a title and multiple boxes.
Each box displays a picture.
The contest owner can associate multiple prizes to each box.

------------------------------------------------------------
[Example] this contest has three boxes, Box 1, Box 2, Box 3.

Box 1 has the picture of a tiger.
Box 2 has the picture of a cat.
Box 2 has the picture of a dog.

Box 1 has prize A, prize B, and prize C.
Box 2 has prize X, prize Y.
Box 3 has prize Z.
------------------------------------------------------------

Each prize can be descicribed in a textarea.

[Example]

<Prize A>
-------------------
Colgate Toothbursh
-------------------

<Prize B>
-------------------
Crest Toothpaste
-------------------

<Prize C>
-------------------
Gift Visa worth $30
Walmart Gift Certificate worth $20
Doggy wear from Petco worth $10
-------------------

To particiate the contest, a player must pay first through PayPal.
Upon a successful payment process, the script sends the player
a payment notification email that contains a ticket#.
Suppose he paid for three boxes.

[payment notification email example]
--------------------------------------------------
Thank you for purhcasing 3 boxes!
Ticket # has been issued.

Ticket #: T12345678
--------------------------------------------------

The player enters the ticket# in the contest page.
Then the contest will allow him to click up to three boxes.
Every time he clicks a box, he receives a notification email
that tells him what prize he wins.
If he clicks three boxes, then he receives three notification emails.
The contest owner also recieves the same notification emails as
BCC(Blind Carbon Copy).

The notification email contains
	1. the title of the contest
	2. the prize that the player wins
	and any static text.

[prize notification email example]
--------------------
Thank you for participating in Happy Morning pic-a-box contest!

Now you win the following prize:

<Prize>
Colgate Toothbursh
--------------------

Sending a prize notification email to the player is the last process
that the script has to do. (The script does not concern about the
prize delivery.)
============================================================

So do you agree? If you do, I'll ask you questions about
other aspects of the script, such as how a box reacts to
player's clicks, and what information the script should
keep track of.
