This project is a one page order form for a web client. There is a list of about 20 products. A colum for the number ordered of each. The next column will calculate the unit price per product, based on the number ordered. The 3rd column will calculate the $ total for the product (multiplying the number by the unit price).
At the bottom of the page, there are 5 totals to print out: TOTAL # OF UNITS ordered (sum of 1st column), NET COST (sum of 3rd column), SHIPPING COST: (based on Country selected from drop-down list and TOTAL # OF UNITS), TAX (17.5% applied only to UK orders), and TOTAL DUE (sum of NET, SHIPPING & TAX).
I am supplying the form validation, so this is not needed. I just need the math computations above.
