I have 4 columns on an issue report entryDate resolveProjectentryDate I have these two columns showing dates, with no problem. I am trying to create a 3rd column to show their difference.But my syntax is wrong - as I am getting nothing. DATEDIFF(date1, date2) DATEDIFF(entryDate, resolveProjectentryDate) I want the fourth column to be the date difference between resolveProjectentryDate and $$Today. DATEDIFF (resolveProjectentryDate, $$TODAY) Either I have the syntax incorrect or I am missing information. Thanks for you help Benetta Perry APS
