Reportviewer DateParameters- Javascript Object Required? Asp.net Content Page?

I've got a report that works great from vs.net, however when I deploy and attempt to run from reportviewer over asp.net, the date parameters do not take. they reset to default and don't impact that report. Also the calendar icon, produces a javascript error "OBJECT REQUIRED" on the below line.


function GetObjectPosition(obj)

{

var totalTop = 0;

var totalLeft = 0;

while (obj != document.body)

{

// Add up the position

totalTop += obj.offsetTop;

totalLeft += obj.offsetLeft; //ERROR HAPPENING HERE.



// Prepare for next iteration

obj = obj.offsetParent;

My reportviewer is inside a content page. My client is ie 7.0

thanks for any help or information.
