Just set the Control Source or the 3rd box to:
=[Text100] + [Text101]
or whatever those other text boxes are called.
You might want to specify that if one of the boxes is null, Access should
treat it as a zero:
=Nz([Text100],0) + Nz([Text101],0)
Also, set the Format property of all 3 text boxes to Currency (or perhaps
General Number) so Access knows they are numeric values.
