Syntax error (New in dax) Using a variable

[akhaliq7]

FINAL DEPARTMENT =

VAR D = RELATED('TABLE'[COLUMN])

IF(

NOT(ISBLANK(D)),

D,

[COLUMN2]

)

Can someone show me why I am getting a syntax error I am new in using DAX so cannot spot it thanks.

I'll answer my own question, you have to use a return keyword before the if statement
