PVC Greenhouse Help!

[Blueberry33]

I wonder if anyone can help me regarding my PVC greenhouse please?
I had this stored in my garden shed for quite a while now and decided to advertise it. A very nice couple came round and I suggested that they erect it first to make sure that nothing was missing. Unfortunately there are some type of screws or fixtures that hold some of the pole together and I cannot remember what they are like so I don't know what I am looking for!
Does anyone have the instructions for erecting this or can tell me what the "fixings are please?

You are probably missing some pvc tees, elbows (they come in different degrees to make the angles you need), 45 degree elbows, and three way connectors. You will have to find the right diameter, 1/2 inch, 3/4 inch.
