Combine Display Rule in Conditional Expression

Not sue if this "Conditional Expression" is correct?

NOT ( R_DRIVE_DISP OR R_FILL_PART

There are two "Display Rules" R_DRIVE_DISP and R_FILL_PART.  They are both basic "Component is Displayed"  types.  I am looking to combine them to work so that the component with the expression is off NOT Displayed when the Driveway Component is Displayed or when the Fill Slop Part is component is displayed. 

So in short do NOT display when R_RIVE_DISP OR R_FILL_PART are displayed.  Am I adding the () and the other parameters correctly?  

I have also tryed

NOT R_DRIVE_DISP AND NOT R_FILL_PART  #This did not really work well either.
