Hello,
Thank you for your reply, but I specify my problem: - Variables in the questionnaire Var1 ## Var2 ## Var3 ## Var4 ## Mean4 ##.##
- In CHECK file (or ANALYSIS) mean4 mean4 = (var1+var2+var3+var4)/4 end
- But sometimes, var2, for example, can fail (blank): in this case, "mean4" is the sum (Var1 to var4) divided by 3!
- My question is, how to count automatically (CHECK or ANALYSIS) the number of variables (var1 to var4) not missing?
Thank you for your help.
