l_concat_1 VARCHAR2(6);
BEGIN
SELECT BULLAE_FLG||CHERRY_RED_FLG||CYANOTIC_FLG||FLUSHED_FLG||GREY_FLG||JAUNDICED_FLG ||MOTTLED_FLG ||PALE_FLG ||PINK_FLG ||PURPLE_FLG into l_concat FROM SKCOLOR;
select normal_flg into l_concat_1 from skcolor ;
IF l_concat IS NULL THEN
IF l_contact_1 IS NULL THEN
return false;
ELSE
RETURN TRUE;
END IF;
ELSE IF l_concat IS NOT NULL THEN
IF l_contact_1 IS NOT NULL THEN
     return false;
ELSE
     RETURN TRUE;
     END IF;
ELSE
RETURN TRUE;
END IF;
END;

HI,
Can you eloborate your problem still more clearly.
Morever i think you need to increase the size of the l_concat, you are concatenating more than 10 flags into a variable of just 6 which will throw an exception,
