/* FUNCTION FOR SHOW HIDE 
Comments added by John M. The below function was causing an error in Firefox. The new show_hide function works 
and was added 10-Sept 07. Assuming three are no other diffiuclties this first show_hide can be removed at a later date

	//alert(window.pageYOffset);
	//alert(document.body.scrollTop);
	if (eval(element+'.style.display=="none"')){
		eval(element+'.style.display=""')
	}
	else
	{
		eval(element+'.style.display="none"')
