/* 
	The two functions are independent of each other...
	* pricrebreak  - is called from the htm form from the QTY input box.
	* fix_colornumber - is called from the is ready function and from the
	drop down color box on the html form. If the color changes or onChange then
	fix_colornumber is called.

	Also: These functions us function.js too. So that has to be included in the html
	web page along with this funtion.

	When isReady is called fix_colornumber is called from within that function to check
	if the color changed or not.

	function pricebreak ----
	Checks out price breaks and assign price 
	Uses function.js also for the makeArry function due to N2 

	In the html or htm form you set the following fields
	hidden  discount="1,19.95,2,19.00,3,18.00,4,17.00,-1,-1"
	hidden  maxqty ="5"  maximum the quantity can be
	hidden minqty = "1"   minimum the quantity can be

	fix_colornumber ----
	This version has the color position function named
	fix_colornumber. This version of the routine gets the 
	position of the color letter to be substituted into the
	part number. The position is sent here from the htm file
	which calls this routine.

	function removeleadingspaces ----
	This removes leading blank spaces in a string and returns string 

	function isANumber----
	This returns 1 if the string passed to it is a numbe or 0 if it is not...

	function whichform-----
	This fills global var n with form name if form name is found...
