//reveals or hides a specified div, using it's id label to identify the layer, and a visibility state of 1 (visible), 0 (hidden) or 2(toggle):
var flashTimeoutID;

function showHide(divID, visibilityState) {
	//get current state:
	var strDOM = divID + ".style.visibility";
	var currentState = eval(strDOM);
	//alert("current state=" + currentState);
	
	//set required visiblity state to the alternate of current state if action is 'toggle' (2):
	if (visibilityState == 2) {
		switch(currentState) {
		case "hidden":
			visibilityState = 1;
			break;
		case "visible":
			visibilityState = 0;
			break;
		}
	}
	//alert("proposed state=" + visibilityState);
	
	//perform visibility setting:
	switch(visibilityState) {
	case 0:
		eval(strDOM + ' = "hidden";');
		break;
	case 1:
		eval(strDOM + ' = "visible";');
		break;
	}
}

//same functionality as showHide, but using display attribute instead of visibility, to allow for compression of display:
function showHide2(divID, visibilityState) {
	var strDOM = divID + ".style.display";
	if (visibilityState == 1) {
		eval(strDOM + ' = "block";');
	}
	else {
		eval(strDOM + ' = "none";');
	}
}

//similar to showHide, but flash recursively calls itself on an x millisecond time delay with the alternate visibility state:
function flash(divID, visibilityState) {
	var strDOM = divID + ".style.visibility";
	var alternateState;
	var timeDelay = 1500; 

	//set visibility according to specified parameter:
	if (visibilityState == 1) {
		eval(strDOM + ' = "visible";');
		alternateState = 0;
	}
	else {
		eval(strDOM + ' = "hidden";');
		alternateState = 1;
	}
	
	//set up the recursive call to this function, using the alternate visibility state:
	var strExpression = "flash('" + divID + "', " + alternateState + ")";
	flashTimeoutID = setTimeout(strExpression, timeDelay);
