// Common JavaScript functions used to calculate and validate form-based ordering forms.
//
// Naming Structure for form items

//
// Items to Customize in this script
// 		- Discount Groups
//		- Required Fields
//		- Sales Tax
//
// Items to add to Order Form
//		- Before codeing
//			- Decide what fields are required.
//			- Product Codes (Client have some?)
//			- Discounts
//			- Shipping Rates
//			- Ship-To States
// 		- To Form Container
//			- Name = '[Whatever]' This script does not use the name but rather grabs the document.forms[0] object. The name is often used in other web apps however... Probably a good idea to make it as descriptive as possible.
//			- Add 'onSubmit="return formChecker(this);"'
//		- Add Hidden Fields
//			- name="ord_quantity_Flat" value=""
//			- name="ord_quantity_Grid" value=""
//
//		- For Each Item to purchase
//			- Hidden Fields with the following properties:
// 				- Items are configured by adding a prefix and a suffux to a product code
//				- Prefix: 'itm_'
//				- Suffixes:
//					- '_d' : Description
//					- '_p' : Price
//					- '_g' : Discount Group (Configured in the matrix below - not required)
//					- '_s' : Shipping Type - Values should be either 'Flat' or 'Grid'
//					- '_q' : Quantity
//					- '_x' : eXtended price (used to show line item expanded totals, ie: 5 @ $20 = $100)
//				- Add to 'itm_[whatever]_q' Select Box, 'onChange="itm_calc();"'
//				- Add to 'itm_[whatever]_x' Input Box, 'disabled onChange="return fail_change();"'
//		- For Each Field that user cannot update (ie: subtotal, tax, shipping, discounts, grandtotal, etc.)
//				- Add 'disabled onChange="return fail_change();"' to container.
//		- For Each Field that should trigger a re-calculation of cat, add 'onChange="itm_calc();"'
//		- Names for other Fields (make hidden if not used.
//			- Number of units in order: 'ord_quantity'
//			- Discount: 'ord_discount'
//			- Ship State: 'Shipping_State'
//			- Shipment Sub-Total: 'ord_subtotal'
//			- Sales Tax Box: 'ord_taxadded'
//			- Shipping Charges: 'ord_shipping'
//			- Order Total: 'ord_grandtot'
