Using Contact Form DB: some pages are written to db and others no

Well, I can′t resolve this, but there is a trick for all who encounter the same problem

Instead of collect all fields in last form, through CFDB, collect data from all forms, exporting records and unifying later. The problem is to identify which records corresponding to each user. Then you can use ‘submitted login’, ‘submitted from’ or ‘contactName’ fields, in the last case it is necesary to put [text contactName] in all forms.

I hope it will help to CFDB and CF7 multi step users
