    I want my macro to evaluate if a field in a SUBFORM is null, and if not,
    allow the user to click an option radio button. If the field IS null, then
    the user shouldn't be allowed to click. Sounds easy enough, right?

    I have this as a condition in my macro:
    [Forms]![frmupdatecaseentry]![SelectedStatusNumber]=6 And
    [Forms]![fromCaseFeatureSubform]![FeatureDateClosed] Is Null

    The problem is that I get an error message to the effect of "Can't find the
    subform 'fromCaseFeatureSubform'" - as though it doesn't recognize that the
    subform is open (the subform IS in fact open inside the frmupdatecaseentry
    main form).

    I've tried using the .form suffix after my subfrom name, but that doesn't
    seem to work. Any other ideas?

    Subforms are not open in its own right, i.e. they are not part of the forms
    collection.

    Try referring to the text box like this:
    [Forms]![frmupdatecaseentry]![fromCaseFeatureSubform].Form![FeatureDateClosed]

    For an explanation, see:
