On my page I have a link that creates a pop-calendar. The user selects the date and the textbox populates with the date. This worked fine for a while then out of the blue it gives me an error. "Object Expected"...everything still works after I close out the error. Anyone know why I would suddenly get this error?

<A style="Z-INDEX: 114; LEFT: 387px; POSITION: absolute; TOP: 300px" href="javascript:calendar_window=window.open('calendar.aspx?formname=_ctl0.txtIntDisStartDate','cale ndar_window','width=250,height=225');calendar_window.focus()">
Select Date</A>
