Write Information Into New Row In Different Sheet But Keeps Overwriting Old Information

Basically I am trying to create a worksheet in which everytime I input information into Sheet 1, it is copied into Sheet 2. I want to have each entry in succession on Sheet 2 such that my first entry would be on Row 2, second on Row 3, third on Row 4, etc. However, everytime I put something new in Sheet 1, it just overrides the information in Sheet 2.

Basically I type in ticket sales in sheet 1, it calculates the prices and keeps a transaction log in sheet 2. But everytime I do a new ticket sale, it just overwrites the previous transaction witht he new transaction information. I've pasted my VBA below:

Sheet 1 VBA:

Code:
Option Explicit

'Form level variables - used in more than one event
Dim intAdult As Integer
Dim intStudentSenior As Integer
Dim intBalcony As Integer
Dim intChild As Integer
Dim sngAmountDue As Single

[Code] .......

Sheet 2 code:

Private Sub cmdSummary_Click()

'Declare Variables
Dim intCount As Integer
Dim i As Integer
Dim intAdult As Integer
Dim intStudentSenior As Integer

[Code] ......
