Hi @terry87,
Please ensure that you have a variable named gender in the dataset. Seems like it is not recognizing the variable.
If it still causes error, you could do the same manually as follows:
- In the syntax editor type: VAR LAB gender ‘Giới tính’. This is a syntax in SPSS where you are trying to label your variable gender to ‘Giới tính’.
- Do not forget to end the syntax with a . at the end.
- Select the syntax that you had typed.
- Press CTRL+R
GOOD DAY!
