Missing Part on sliding door

A quick learner from Vacaville, CA says:
Your product number 82-217A is the latch I found that is broken on my door and I will replace it.

But, what part do I need to install on the sliding part of the door to make this functional? The part is missing and I saw three holes on the door.

Thank you. Maria~

Thanks for posting, Maria. I don't know which part it is that you're missing. Can you give me more information? What is this part's function? Where exactly was it installed? Seeing a picture or two of where it was installed may help, as well.
