Apparently variable C14 is a character variable with values 1 2 3 4 and so it must be in the CLASS statement; or you have to create a numeric variable with the same values and use that.

The variable C14 is probably a character variable. To see the type of the variable, use

proc contents data=HAVE ;
   ods select Variables;
run;

To solve the problem, use a CLASS statement:
class C14;
