Unable to set link auto name

When i link a doctype inside another doctype i would like to use one of its field as a the showing part in the link input. So I set the auto name to name1 but it still does not show


@YuaShizuki can you check this How to show Description in Link fields instead of Id?? Is it that do you is trying?

If not, do you can elaborate your question?

Yeah and the last solution is missing.

@YuaShizuki, it is not possible, current!
