StringVar combinedPC = '';
if PreviousIsNull({Command.PROJ_ID}) or (not IsNull(({Command.PROJ_ID})  and combinedPC = '') then
  combinedPC := {Command.PROPERTY_CODE}
else
  combinedPC := combinedPC + ' & ' + {Command.PROPERTY_CODE};
combinedPC

For the part (not IsNull(({Command.PROJ_ID}) it says a boolean is required.
