Hi
So is the form like this:
id-of-content-type-period || price 1 || price 2
And is the List view like this:
content-type-period[some-data] || price 1 || price 2
Sounds to me like you want to
1
create the period content type that stores values ie
week1-2
2
Create your main content type that has a selec dynamic field that pulls in the id of period content type for the user to select
ie
SELECT a.title AS text, a.id AS value
FROM #__content AS a
INNER JOIN #__cck_store_form_period AS b
ON a.id = b.id
WHERE a.state = 1
AND catid = somevalue
3
Then in your main list search view you can add the join field
Join table on the id stored in select dynamic with the id in period table and then add the desired period fields to your list or item view.
If your period fields have padlock locked then you need to create new period fields that have storage location identical to the fields you are trying to access
Might be a little wrong in places but hope thy sets you on the right track
