Preparing:

  • Get selected objects
  • pick first selected
  • get its class id
  • get all attributes of that class
  • loop for all attributes

Interesting:

  • check for attribute type RECORD

  • get attribute name

  • GET_REC_ATTR_ROW_COUNT

  • check if successful

  • show result (count) and exit

  • if no attributes of type RECORD were found: Report error
