		if(page){
			page.open("GET",url);
			page.onreadystatechange = function() {
				if(page.readyState == 4 && page.status == 200) {
					object[i] = page.responseText; 
				}
			}
			page.send(null);  // #1--IF THIS REMAINS, CODE EXECUTES PERFECT
			alert(object[i]);
			document.getElementById(roomslist[i]).setAttribute("bgcolor",object[i]);
			//alert(object[i]); // IF THIS REMAINS AND #1 IS COMMENTED, EVERY ELEMENT CHANGES TO 0 (from object array)
		}
  }

	//   THIS WORKS
	for(var i = 0; i < roomslist.length; i++){
		if(roomschecklist[i]){
			document.getElementById(roomslist[i]).setAttribute("bgcolor","00CCFF");
		}
	}*/


IF BOTH #1 and #2 are commented (no alerts), the code does nothing.
