I have a cck text field field_review_comments which I want to automatically generate the title for the node. I am using the token [field_review_comments-raw] in order to generate the title, but Automatic Nodetitles module makes the whole content of the field as the title. I only want the first 30 characters from this field to be part of the title. Is there some way to trim it down to the first 30 characters?
Also what is the difference between raw and formatted? I am not sure which token to use, [field_review_comments-raw] or [field_review_comments-formatted]
