months, intervals and integers

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?
