Let's say you have this scenario:
You want to enable parents to be able to order one or more tickets of a fund raiser event when they are registering their child into one of your main programs.
For example, you want to be able to sell 1 or more tickets to families to a Movie Night, in the same process when a parent is registering their daughter into Spring Softball, or son into Football, etc.
Here's how:
1. From the Admin Site Map, go to Programs > Configurations > Add-ons
2. Click the Add Buy Item button.
3. From the Add Buy Item page, change "Variation 1" to "Yes" and for the description type "Quantity".
4. When you click the Add button to add the Buy Item, you will be dropped onto a "Variations" tab.
5. From the Variations tab page
add 1 as the Variation Name and Variation Value and $0.00 as the Cost Differential since the Base Cost you added on the Add page is the value for 1 ticket.
add 2 as the Variation Name and Variation Value and type the value of 1 ticket as the Cost Differential since you are adding the value of 1 ticket to the Base Cost (making the total cost for "2" the base cost plus this variation value you typed). For example if tickets are $10, then the base cost is $10, and you type $10.00 for the Cost Differential when "2" tickets are selected.
add 3 as the Variation Name and Variation Value and type the value of 2 tickets as the Cost Differential since you are adding the value of 2 tickets to the Base Cost (making the total cost for "3" the base cost plus this variation value you typed). For example if tickets are $10, then the base cost is $10, and you type $20.00 for the Cost Differential when "3" tickets are selected.
and so on.
