Sql Developer Oracle12 c--not enough values

Hi
I am getting a "not enough values" error in SQL developer. I am trying to enter  three user-prompted values into a table that contains five fields. Here is the query:

INSERT INTO  APPEALS (APPEAL_ID, CRIME_ID,FILING_DATE, HEARING_DATE, STATUS)
VALUES  '', &CRIME_ID, &FILING_DATE 'MM-DD-YYYY' , &HEARING_DATE 'MM-DD-YYYY','';

Appeal_Id is a sequence value; &CRIME_ID, &FILING_DATE, &HEARING_DATE  are substitution variables.

What am I doing wrong here? Any help would be appreciated.

Thanks!
