CF8 - Save form in DB

Hello everyone,
I have a problem when I have to save form data in a database.

This is my load section in form:


in this submit section I have entered this structure:


This is my db:


Email sending works perfectly.
Instead for saving on database I think I'm wrong to set the settings; i insert "read data" to control if the email is already present in the database.
if it is present, a warning message appears that the registration for that email is already present, otherwise "save data".
These are the settings:


what settings should I enter to save the data on the database?
I haven't found a tutorial for saving data in chronoforms v8.

Thanks to everyone who will try to help me

Hi,

you need to enter {data:} in the "Data Source", you may also need to set the "Primary key" behavior, both in the "Save Data" settings

Thanks Max but I still have problems.
this is the db:


so i have changed the settings:


this is the error:


is it possible to create a tutorial like that of sending mail?

the "Data source" should be:

{data:}

The Primary key should be:

id

it's possible to create a tutorial, but for now it should work for you with the settings here

I put the mail module before the read module:


these are settings in "save data":


Now no error appears and the mail was sent but the saving to the db does not occur

are you saving a new record or updating ? do you have the form "Debug" enabled ? what does it show ?

if this form is only for registered user, how can i insert NAME and email directly reading data from table user of db?

use {user:name} and {user:email}

THANK YOU!
