What's wrong with the following statement. It keeps returning Null?

I've never used an SQL if statement before.  @DaysUsed does in certain circumstances  = Null but I need it to be zero for later calculations.  @DaysUsed is a int.  I don't understand why if the statement is true it doesn't set the variable to 0?
If @DaysUsed = NULL 
 
Begin
Select @DaysUsed = 0
End
 
Select @DaysUsed
