I would like you to help me in this subject.

I'm new in Visual Foxpro 5.0. I have a form with the following fields, not exhaustive :

Sexe : Male or Female (M or F)
Family situation : married, bachelor, divorced (M, B, D)
Number of children (1, 2 , 3, ...)
Number of parts

I want to determine the number of parts after filling the three first fields.

For instance :

If sexe = Male and family situation = Married and number of children = 2 then the number of parts = 2


I would like, after determining the number of parts, to enter the result in a texbox named PARTS.

THANK YOU FOR YOUR HELP


NB. My english is not good because I speak french.
