    Hi there
    I have a form relating to a table "vehicledetails" with a page displaying a
    list "availablevehicles" and another page showing a subform relating to
    another table "vehiclebookings" and displaying a list "currentbookings".
    When I perform an action to place a booking, the "availablevehicle" list
    updates immediately, however the "vehiclebookings" list dosent update unless
    I close and reopen the Form.
    Have tried refresh and requery, to no avail. any ideas
    Cheers Ross

    Are you sure you are doing a Requery on that sub form?

    You can usually do a requery like

    me.MySubFormContorl.Requery

    The above usually will do the trick. You could I suppose FORCE a requery on
    the actual sub-from also. If the above don't work, then try the actual form
    object, like:

    me.MySubFormControl.Form.Requery

    Note how we distinguish between the sub-form control, which is just a
    control like any other on your form. (this means you can even set what
    "form" the sub-form control displays at run time. So, don't confusing the
    concept of sub-form being something other then a standard control on your
    form.

    Anyway, if the neither of the above works, then something else is going on.

    I would perhaps force a update of the "main" forms record BEFORE I run any
    processing code, and THEN do a requery on the sub-form as above.

    So,

    me.Refresh - force a disk write of the main form
    - this assume your code is running
    - in the main form
    --- now call your update stuff......
    me.MySubFormControl.Requery

    The above should work. As mentioned, you might change the above to

    me.MySubFormControl.Form.Requery
