This has been racking my brain all day, and I can't work out how to do it... can anyone help?
I want to use the jQuery Calculation plugin to perform a calculation from input boxes on my site...
For example:
Input boxes: Number of guests and Number of servings
100 or less guests: £180
+
£1 per each additional guest (101+)
+
£0.60 per each additional guest serving
Calculation: would be £180+(additional guests x £1)+(total guests x servings @ £0.60)
Example: 112 guests with 2 servings would be £180+£12+£67.20=£259.20
Can anyone help at all?
Thanks in advance
