    Make field in a form active or inactive based on the value of a calculated field

    I have a query that is calculating a client's eligibility for services. This field's output is either Yes or No depending on data from a series of other fields (automatically calculated).



    On my form, I would like the "Interested" field to be active only when Eligibility is Yes. Something around these lines:

    Code:
    If [Eligible_PROSPollock] = "Yes" Then
    Interested_PROSPollock.Enabled = True
    Else
    Interested_PROSPollock.Enabled = False
    End If
    I've tried putting this code in a few different event options, but I cannot get the field to dynamically switch from active to inactive or vice versa without manually clicking Refresh. I'd like the field to automatically activate or deactivate each time the Eligibility field changes from Yes to No or vice versa. Reminder, the Eligibility field is never changed by the user manually, it is also an automatically calculated field (iif statement from the source query).

    It seems to me that the Current event is where you want to place this code. Then in the after update even any control on the form where the calculation would be updated you need to requery the form so the current event fires again, or just update the calculated control.

    HTH.

    I'm trying to avoid putting the code into every single control on the form. What would I use to "requery the form" and what do you mean update the calculated control? The control seems to be updating on it's own. Meaning, when the calculated value changes, the recalculated value does​ show up in the text box.

    Yep. That's what I do as well. Sometimes it is unavoidable. But your are correct, if you can avoid it, do so.

    The only code you need should be : Me.Requery If you put this on the after update event of every control, it should refire your form's current event and set the active/inactive control you are trying to calculate.
