    Access 2003.
    I have a field on a form that shows the number of days between 2 dates

    =Datedif("D",[Arrive],[Depart]).
    This shows the information in a subform in datasheet view. I have a
    text box on a form and would like to show the total of the dates. I
    have tried placing a box in the footer and referencing that with a sum
    total but the count is incorrect.

    TIA
    Jerry

    Jerry,

    Summary fields must reference fields in the RecordSource. For example, if
    your first calculated control is named MyDateDiff, then:

    =Sum(MyDateDiff) will not work. Use the following instead:

    =Sum(Datediff("D",[Arrive],[Depart]))
