You guys are great. I actually got it to work with the following:
{@dtCompleted} = {?Completed_Date_ Range} and
IsNull({TASKS.PRIORITY})and
IsNull({TASKS.TYPE}) or
{@dtCompleted} = {?Completed_Date_ Range} and
IsNull({TASKS.PRIORITY}) and
not ({TASKS.TYPE} in ["BI Request", "BI Production Requests", "BI QA Team"]) or
{@dtCompleted} = {?Completed_Date_ Range} and
not ({TASKS.PRIORITY} in ["Documentation only", "Project"]) and
IsNull({TASKS.TYPE}) or
{@dtCompleted} = {?Completed_Date_ Range} and
not ({TASKS.PRIORITY} in ["Documentation only", "Project"]) and
{TASKS.TYPE} <> "BI Request" or
{@dtCompleted} = {?Completed_Date_ Range} and
not ({TASKS.PRIORITY} in ["Documentation only", "Project"]) and
{TASKS.TYPE} <> "BI Production Requests" or
{@dtCompleted} = {?Completed_Date_ Range} and
not ({TASKS.PRIORITY} in ["Documentation only", "Project"]) and
{TASKS.TYPE} <> "BI QA Team"
Thanks guys, have a happy holiday, if you're into that type of thing
