    I have a 2 fields in my table/Form field XYZ and ABC
    if XYz is true then ABC needs to be true
    if XYZ is true and ABC is missing, then ABC will have a "missing" value

    I have the following statement as a control source for my text box on my
    form but its giving me an error.
    =IIf(IsNull([ABC] & [XYZ])=True,"Missing",[ABC])

    Try this

    IIf([ABC] Is Null And [XYZ] Is Null,"Missing",[ABC])

    But from your explenation I can't fully understand what you need
    if XYz is true then ABC needs to be true
    if XYZ is true and ABC is missing, then ABC will have a "missing" value
    (but the first condition been applied, so there is no need for this
    condition, XYZ is true, Now what if it False?)

    stay saved for a longer time, so other can benifit from it.

    Good luck

    Part of your problem is that you're referring to ABC in the IIf statement
    that's setting ABC's value. As well, if you're expecting ABC to be a boolean
    value (True/False), it can't have a value of Missing.

    What happens if XYZ is False? The following assumes ABC will be set to the
    word False.

    IIf(IsNull([ABC]) AND [XYZ],"Missing", Format([XYZ],"True/False"))
