I need a form that calculates a quote based on the combination of 5 shipping zones and 5 box sizes.
* Each state is assigned 1 of 5 shipping zones to calculate shipping.
**Ounces here determine the box size or combination of boxes. Each box is assigned a shipping price.
NOTE: The box sizes have gaps in the volume they hold, so we need functionality to auto-calculate the combination of boxes based on the user's input in the "Volume (fl oz.) Needed" field.
Example: User inputs 75oz. Form auto-calculates the need for 2 small (40oz) boxes.
