I am getting unknown subskt errors

i am getting unknown subskt errors when using a hierarchal entry, i am trying to bus out of it. i dont know what i should try.

i found out the problem but i dont know how to fix it when i right click the schematic to show the netlist nothing happens when on my other apprentices program (that does work) it brings up some lines of code. does anyone know how to resolve this. i have tried deleting and remaking it.
