Email autocomplate

hello
​
when i select auto add filds data in email
it just format selected fields to email
​
but what if i have a loop to added in email as two or three data unit from multiplier
​
how can i format them like auto formatted style?
​
in the description it is said {AUTO_FIELDS} to use which does not work
moreover there is auto template option
how it works is this what i need to format the data?
i mean with {label}

YOUR TEXT HERE: {data:fieldname}

​
For repeaters it depends on how you named them, but you should name them
​

groupname[{var:area_repeater#}][fieldname]

Then you have a LOOP (NOT loop event) set to "return result as var only", data source {data:groupname}, and in the loop you have

RESULT GROUP NUMBER {var:loop#.key} <br>
LABEL ONE: {var:loop#.row.first_field_name} <br>
LABEL TWO: {var:loop#.row.second_field_name} <br>
etcetc
<hr>

​
Then in the email you use {var:loop#} where you want that text shown.
​
Replace all the # with the correct numbers.
