This question is really broader than the title. Here's what I'm trying to accomplish for an order form:
Line 1: Number of products ordered (A).
User indicates how many products he wishes to order. The total number of products ordered adds up to A.
Line 2: Product Cost (C).
A * 4.95 (which is the cost per unit) is the product cost (C). I want C to be two decimals after the decimal point, so if four units are ordered, the cost is $19.80, not 19.8 (or 19.8000000000001)
Line 3: Shipping (S).
If they order one unit, the shipping cost is $2.50
If they order 2-5 units, the shipping cost is $5
If they order 6-15 units, the shipping cost is $10
Line 4: Overall cost.
C + S
Can anyone tell me how to accomplish this? And how do I learn how to do this on my own?
