    Date Field

    Good day! i have 2 fields with row source: SELECT SowTags.[Sow Id], SowTags.[Due date] FROM SowTags ORDER BY SowTags.[Sow Id];


    field 1 shows the [SowTag]
    field 2 shows the [Due date] and is not enabled

    then i have a text box =abs([DateEntered]-[Due date]). result would be either #Type! or a date like Aug-4-16

    Thanks in advance!

    You have two comboboxes on form? Why would two fields/comboboxes have the same RowSource?

    I expect both actually have value of [Sow Id]. But would have to see other combobox properties to confirm (ColumnCount, BoundColumn, ColumnWidths).

    Textbox expression can pull [Due date] from combobox column by referencing column index. Index begins with 0. Name combobox different from field, like cbxID.

    =Abs([DateEntered]-[cbxID].Column(1))

    Note that calculation will not include start date. 12/30/2019 - 12/27/2019 will return 3, not 4. Therefore 12/27/2019 - 12/27/2019 will return 0. In your case, this might be what you want.


    Advise not to use spaces in naming convention.

    What's the question? You realize your calculation results in a number, not a date (the number of days between the 2 dates). The textbox should not be formatted as a date. The error may result when one of the fields is Null (blank).

    ComboBox1: would show [SowID] (enabled, ColumnCount 2, BoundColumn 1, ColumnWidth 1";0")
    ComboBox2: automatically sows [DueDate] (thanks for the advise on no spaces, NOT ENABLED, Format ShortDate, ColumnCount 2, BoundColumn 1, ColumnWidth 0";1")

    I removed ComboBox2

    I typed unto TextBox1 your suggestion =Abs([DateEntered]-[SowID].Column(1)) but it would change to =Abs([DateEntered]-[SowID].[Column](1)) and would still show #Type!

    Thanks in advance!

    The outcome i was hoping for was the difference between two dates, which would be a number. Yes the textbox is a general number and not formatted as a date. Thanks for the reply!

    Sorry, have to convert combobox string value to date:

    =Abs([DateEntered]-CDate([cbxID].[Column](1)))

    Yes, Access will throw in the [ ] if you omit.
