Unfortunately the fields you included in that Import/Export were text fields and thus had the Binding tab available in the Object Palette.
Fields that are of type Calculated - Read Only do not have the Binding tab, so to get around that, I defined my variable to be Read Only, and added my calculation to the calculate script. The Binding tab was available and thus allowed me to bind my output.
Problem solved.
Thanks anyways,
