I have a tbltimesheet. It has starttime and stoptime my query calculates the difference between starttime and stoptime. I am trying to limit the data to dates between two certain start dates 10/1/2013 and 10/30/2013 for example. I change the starttime to a datevalue([starttime]) There may be nulls in the query so I filtered them out with not null. Everytime I try to limit my results I get a too complex error message. It works fine for all of the records. Thanks for the help.
