Hi Xianwen
If the variable is numeric you cannot enter NA.
You could do either of two things, assign a value (or of the feasible range for the variable, i.e, if all values are positive, then you could assign -7 as NA) or use one of Stata's 27 numeric missing values.
See -help missing- for more on Stata's missing values
hope this helps,
Ronnie
