add button disappeared from my form

[NCD]

I've made a second REF_ROWS("Child_slice", "id_Parent")

So I can have a different inline view and all works fine, but I cannot seem to add entries of my child records through my parent form.

solved it by deleting all the ref rows and let the system create one again start over!
