Not really :-S
It's a little bit tricky ;-)
It should be a form not a edit page of an existing article.
The User in the backend set up default values
Example:
Field min_range
Field max_range
In Siteform is a field called length
Now i want to check with javascript, is the length that the user has filled in min_range and max_range
length <= $cck->get('min_range')->value->from->articleId(50);
The form should be submitted.
The "Admin" put the values in the article and not in Seblod.
Seblod is only for the superadmin :-)
And the Admin could edit values without knowledge of seblod.
Hope it helps :-)
