Scope issues that I cannot seem to get through

[2levelsabove]

function isSpecBook(fileid)
{

 	var	count = 0;

	if (window.XMLHttpRequest) {
		var req = new XMLHttpRequest();
	}
	else if (window.ActiveXObject) {
		var req = new ActiveXObject("Microsoft.XMLHTTP");
	}




req.open("GET", "isSpecBook.php?FileID="+fileid+"&json=1", true);
	req.setRequestHeader('Content-Type', 'application/json');
	req.send(null);	






	req.onreadystatechange = function() {



		if ((req.readyState == 4) && (req.status == 200)) {
			var jsonSpec = eval('(' + req.responseText + ')');




            for (var x = 0; x < jsonSpec.length; x++) {
					             				
            	count=1;

alert(count1); // count within function
					             					
					        		
					             				
	                                              }

}


	}//req.onreadystatechange = function() {


alert(count);//count outside function
}//function

 

 

For some reason I am having scope issues. The count inside the function seems to work fine but the one outside right before the end of function never gets set.

 

please help.

 

thanks
