Count field groups

CB Auto Actions understands field groups just fine. The problem is you're conditioning against the original field which isn't used anymore beyond being a blueprint for CB Field Groups. You need to use CB Field Groups substitutions to pull values out of the field group or you need to parse the JSON yourself in a Code condition. Example of how to read a field group field as follows.

Field Group = cb_grp
Field = cb_int
Substitution = [FIELDGROUP__ROWNUMER__FIELD]
Result = [cb_grp__0__cb_int]

That will give the value of cb_int in cb_grp for the first row of the field group.

Ok , so
As far as I understand for the conditions it will be like
[cb:parse function="clean" method="int"][cb_fieldgroup__3__var1_cb_field][/cb:parse]
[cb:parse function="clean" method="int"][cb_fieldgroup__3__var3_cb_field][/cb:parse]
but for the AA->Action, how do we use substitutions since the DATE_FIELD is also inside FIELDGROUP

[cb:parse function="date" date-format="Y-m-d" time="false"]now[/cb:parse] doesn't update the DATE_FIELD
 

You are not going to be able to update a date field within a field group easily using the Fields action. The only way would be to process the JSON yourself. I do not recommend using field groups for complex usages like this. Row numbers are not static that 3 could be a 5, a 10, a 9, or even 0 depending on the rows.

Taking the DATE_FIELD out of the GROUPFIELD is it going to make it work?

So either I have to proccess JSON or take both fields out of GROUPFIELD, correct?

Correct.
