Hi, I am passing a url param to a popup window like ... popup=window.open('#app#/page.cfm?UserID='+document.page.UserID.value,'popupwin','width=400,height=300,toolbar=0,location=0,directories=0,status=1,menubar=0,scrollbars=1,resizable=1'); document.page.UserID.value is ALWAYS SELECTED. Sometimes ColdFusion says that #url.UserID# is not defined. Sometimes no error is shown and the code works but I receive a cferror email that says #url.UserID# is not defined. This is running on solaris. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Structure your ColdFusion code with Fusebox.
