Hello Monks (been a while!),

I've been steadily falling for FormFu and DBIx::Class::Schema, but have finally found something that i'm either not describing to the search engine spirits correctly (probable) or no-one has tried to do before (unlikely). As such I request your aid on this hurdle.

Situation is as follows :

• retrieving 4 tables to show as a single update form
• tables are box,batch,forms and issues
• a box has many batches which has many forms which may have many issues
• management requires batch level summaries whilst setting batch level variables ( dates, times etc)
• forms need to be totalled based on a condition (entered != null) for information purposes

Essentially, I'm trying to get sum(form.entered is not null) from within the form fu repeatable element. YAML form specification as follows:

---
indicator: submitted
elements:
- type: Hidden
  name: count
- type: Block
  tag: table
  elements:
  - type: Repeatable
    increment_field_names: 1
    nested_name: SubBatches 
    counter_name: count
    elements:
    - type: Hidden
      name: batch_uid
    - type: Block
      tag: tr
      elements:
      - type: Block
        tag: td
        elements:
        - type: Label
          name: batch_id
      - type: Block
        tag: td
        elements:
        - type: Label
          name: checkable
      - type: Block
        tag: td
        elements:
        - type: Select
          empty_first: 1
          name: user_id
          model_config:
            resultset: User
            id_column: user_id
            label_column: user_name
            attributes:
                order_by: user_name
      - type: Block
        tag: td
        elements:
        - type: Label
          name: form_count
      - type: Block
        tag: td
        elements:
        - type: Label
#right here i want sum(form.entered is not null) where batch_uid = cur
+rent
          name: forms_entered
      - type: Block
        tag: td
        elements:
        - type: Label
#and here, get sum of issues from forms in batch where batch_uid = cur
+rent
          name: issues
      - type: Block
        tag: td
        elements:
        - type: Text
          name: forms_to_check
      - type: Block
        tag: td
        elements:
        - type: Text
          name: num_checked
      - type: Block
        tag: td
        elements:
        - type: Text
          name: errors
      - type: Block
        tag: td
        elements:
        - type: Text
          name: forms_wer

Firstly i'm at a loss as how to uniquely identify a section of forms from within the repeatable element, and secondly how to actually total the values from that element.

Any and all help would be greatly appreciated.
