in v5... each mapping is equal to a input name
if the field is in subform, then the field id need to prefix with the id of subform lah
this allow u to import to several tables based on the form binder in the form
tht y i told u ..u can even import user.. or using bean shell for import
becoz the import is handle by the form binder
the validation is handle by form as well
account_id is the field id
account_crm is the subform id
it is follow the form input name
when u check the input field in ur subform using firebug.. u can see this
