Help with Defining a new Concurrent Program using Parameters

Question

I wrote a very simple sql script and I want to register it as an Oracle Concurrent Program. I included a parameter field in the sql script to allow the entry of value to determine the number of days prior for the script. The script runs successfully in SQL*Plus, but when I try to register it as an Oracle Concurrent Program I get the following errors below:
This works in SQL* PLUS
SELECT emp_id, amount
FROM tblSalaries
WHERE hire_date > SYSDATE-&Days;
Enter value for Days: 7
old    3: hire_date > SYSDATE-&Days
new  3: hire_date > SYSDATE-7
And it provides my results....Although when I register this as a concurrent program and assign the parameter in the setup, and run the concurrent program and enter the number in the parameter field, the job completes in ERROR with the following:
Enter value for Days: EXEC FND_CONC_STAT.COLLECT;
hire_date > SYSDATE-EXEC FND_CONC_STAT.COLLECT; and
ERROR at line 3:
ORA-00933: SQL command not properly ended If I put single quotes around '&Days', in line 3, I get a different error:
ERROR at line 3:
ORA-01722: invalid number Do you know what could be the problem?
Thanks for reviewing!
