Hi,
Please can you help me.
I have two datasets each with 3 variables. in the first, the variables are: codemen_1, person and b4_pl_ (age of old members). in the second, the variables are: codemen_1, individual and b4_ (age of new members). I want to merge the two dataset so that I have a single with 3 variables: codemen_1, individual and b4 (age of all members).
