System missing value

#1
I have a data from 340 respondents that I key into SPSS.
But the problem is the result of descriptive statistics show that the system have one missing data eventhough there is no data missing ( i filled up every single row and column). And SPSS say the total sample size is 341 instead of 340. Why this happen ?

Check row 341 whether it is filled with system missing values. In that case, delete row 341.
If there is no row 341 with system missing values, there should be some row in between
which contains no data.

With kind regards
