when updating data at form 1, a new record is created at form 2

some fields are directly transfered from form 1 to form 2

this is acomplished with "add record".

but form 2 has a field "A" wich value depends on the value of field "B" at form 1. That value has only two possibilities and should be obtained by a "if then else" with the value of field "B" of form 1.

how can this "if then else" work inside "add record"?
