function ShowElement(element,button,buttonon,buttonoff,elementlist,hideothers,buttonlist){ 
// Script Author: Mark Rossmore
// Shows and hides whichever element is displayed
// Changes the status control button for the element
// Fields:
// 		ELEMENT: The name of the actual document element that needs to be hidden/shown.
// 		BUTTON: The name of the element's control button (usually a plus-sign or minus-sign graphic that points to this function).
// 		BUTTONON: The button graphic that shows when the element is visible. In most cases this will be a "Minus-sign" to show that it can be shrunk.
// 		BUTTONOFF: The button graphic that shows when the element is NOT visible. In most cases this will be a "Plus-sign" to show that it can be opened.
// 		ELEMENTLIST: An array of all comparable elements that forms the basis for the HIDEOTHERS function
// 		HIDEOTHERS: If set to TRUE, this will run off the array called <elementlist> (this is created elsewhere) and hide all other elements in that array except for the one named here in the "ELEMENT" variable.
