For loops in model clause

Hi list,

I'm playing with the model clause but, I'm having some trouble with a rule using a for loop.

dt_elig is a date column in the source table. The error I get is : ORA-32626 Illegal bounds or increment in MODEL FOR loop. Any idea about what I'm doing wrong?

*

FOR* dt_elig *FROM* to_date('01-Dec-07','DD-Mon-YY')
* TO* to_date('01-Jun-08','DD-Mon-YY')
*INCREMENT* numtoyminterval(1,'MONTH')
