Hi folks

I've got the following table and view and I don't know exactly how to get what 
I want.

The table contains integers for the number of months.
I want the view to convert those month integers to intervals that it can 
add/subtract from a date.

create table crm_scripts (
  cs_id		int4 primary key,
  cs_title	varchar(100),
  cs_age_min	int4,
  cs_age_max	int4,
  cs_script	text);

create view crm_script_details as 
  select *, 
    CURRENT_DATE-cs_age_max as start_date,
    CURRENT_DATE-cs_age_min as end_date,
  from crm_scripts;

If cs_age_min is 6 I need start_date to be CURRENT_DATE-'6 months'::interval

Any ideas?
