Making fields conditional on Data Entry Forms

[Jared]

I have a data entry form with several combo boxes; I would like to make a
text box conditional on the value of a combo box above it. I only want the
text box available if the combo box is set to a specific value. Otherwise, I
want the text box grayed out/ unavailable. Is this possible? How do I
structure an expression for this?

And what is that 'specific value'?

Set that text control's Enabled property to No (grayed out).
Code the combo box AfterUpdate event:

Me.[TextControlName].Enabled = Me.ComboName = "What?"

Place the same code in the Form's Current event.
