Subject:      is variable aspect a constant?
Content-Type: multipart/alternative;

Hello!
 
I have a question about defining variables that are used in test-retest correlations.  
 
If I have a variable that is computed under the If statement, does that "If" condition make the new variable a constant?  for instance,  i have a computed variable "resefc" that is computed as the sum of responses 63-65.  I have computed  two other variables "resefc1" (which is resefc IF assess=1) and "resefc2" (which is resefc IF assess=2). 
 
in this case, does the "assess" variable act as a constant?  I ask because I am unable to do bivariate correlations on resefc1 and resefc2;  i keep getting a message that indicates "one or more of the variables is a constant".  
 
any help would be appreciated.
