Hi, everybody:
I have a matching problem and wish you could give me a hand:
The two datasets have the same varible name and lable names, so I relabeled
all the varibles in the second dataset and in additon, I renamed all
varibles excepted the matching keys (three of them) in the second dataset;
then I used merge command to merger them, but I always get the message:
Label ... already defined, and the program stops.
Why..........................????????
