You will liekly need to replace the whole window section, if the f*cks cut the plastic (see-thru) part. But you don't need a whole new top as stated. However in the meantime, find some quality 100% clear packing tape. I have done this before as a stop gap measure, and while not pretty, it is fairly effective, not as noticable as you might think, and lastly real cheap. If you try this, clean the entire area around the sliced section with rubbing alcohol, and use tape on both the inside and outside.
