Clair de lune moses basket help required!

We have kindly been given one by a friend but im baffled by which hole the hood poles/plastic bits are to be secured using. Have tried googling for instructions but no joy. My friend had it screwed into second row of holes on third from the right of the handles but that seems far too forward so ive moved it to second row down and 2 to the left but still doesn't seem right. Any ideas?
