Cant find anything wrong with this code but it still errors

Ok.. below is my code which appears to me to be flawfless... BUT

this is the call of the function

LERG_CLLI(recMatch.LEC_NPA, recMatch.LEC_NXX, recMatch.MCI_NPA, recMatch.MCI_NXX)

the following section is the function the above calls....

FUNCTION LERG_CLLI(sLECNPA IN VARCHAR2, sLECNXX IN VARCHAR2,sMCINPA IN VARCHAR2, sMCINXX IN VARCHAR2) RETURN VARCHAR2 IS RET_LERG_CLLI VARCHAR2(11);    BEGIN
       SELECT LEC_SWTCH_CLLI INTO RET_LERG_CLLI     FROM CIS_COLLO_T
    WHERE (LEC_NPA = sLECNPA) AND
(LEC_NXX = sLECNXX) AND
(MCI_NPA = sMCINPA) AND
(MCI_NXX = sMCINXX);

   RETURN RET_LERG_CLLI;
END; this is the ERROR message I get...

(1):PLS-00306: wrong number or types of arguments in call to 'LERG_CLLI'

I do not see how this is an error????
