//validation and other javascript functions.
/*
function: validate()
			function validate(oControl as object, vType as String)
			this function gets passed the object that is to be validated, and the 
			type of validation to be performed on it.

function: MM_findObj, MM_showHideLayers, MM_preloadImages, MM_swapImg and MM_swapImgRestore
			these are dreamweaver layers functions.  not pretty, but robust and		
			browser compatible
		
function: expandIt()
			used to expand and contract list items

function formatDecimal(number, boolean, decimal)
			this function is used to format a decimal to
			a specified number of places. default is 2

function formatValue(argvalue, format)
			used to format a currency value to a format
			specified by the user (in the form £###,###,###)
			NB: This function sits on the back of the
			formatDecimal function
function RandomImage
			this function selects a random image for the left side of the
			screen
function OpenWindow (reportname)
			Opens a new window and displays the requested report	

function hideAllSelects, showAllSelects
			Used with layers, to hide and show selects beneath layers.  This is because
			they are treated as separate documents by ie so dont conform to zindex.  duh.
