ACCEPT PID PROMPT 'PLEASE ENTER THE EMPLOYEE''S ID #: '
ACCEPT PLN PROMPT 'PLEASE ENTER THE EMPLOYEE''S LAST NAME: '
ACCEPT PFN PROMPT 'PLEASE ENTER THE EMPLOYEE''S FIRST NAME: '

INSERT INTO MY_EMPLOYEE
VALUES (&PID, '&PLN', '&PFN', LOWER(SUBSTR('&PFN',1,1) || SUBSTR('&PLN',1,15)), &PS);

[gsprince]

check whether the number of columns in your table (my_EMPLOYEE ) is 5, if not write the DML as
Insert into my_employee (col1, col2, col3, col4, col5) values (val1, val2, val3, val4, val5) ;

If this is not the case, post the error message.
