Ceiling lights

[Anonymous]

Hi,

I am trying to place lights on my ceiling and when i try to create an array or copy  i keep getting an error.

Ive attached the error below. It happens with all the light fixture and i tried changing the ceiling type but still didnt work.

It is telling me there are multiple instances ontop of eachother but it is a single item and once i create the array it piles them up above the origiinal one 

Thank you

Thank you,

I am now having problems when I render. The materials have a very weird greyed texture to them. In this image the wall should be white.
