To make a payment, click on one of the appropriate amounts to add the number to your shopping cart.  The shopping cart window will open, and then you can adjust the "quantity".  You can then "continue shopping", or close the shopping cart window and select the next number.  When your cart opens it will add this second number, remembering what you entered before.

For example, if you are paying $2450 - start by clicking on "$1000" and then change the quantity in the shopping cart to "2".  Then click "continue shopping" and click on "$100" and change the quantity to "4", etc.
