Dear,

I am trying to replace all my "n.a." values into zeroes for my variable c20_28. However, when I try to do this, I get a type mismatch. The type of the variable I am trying to change is Double. Could you help me out? this is my code:

Code:
replace c20_28 = 0 if c20_28 == "n.a."
type mismatch
r(109);
thank you very much!
Timea
