I'm having trouble with finding the screws that go into the long pole parts. I know that I have to connect the silver pole with the bigger black poles, and I'm having a hard time finding how to connect the two (washers and screws, etc). Does anyone have pictures or can post some on that? I'm having issues with it and I have not been able to figure it out. The book it came with doesn't show where and which parts to put into the actual poles.
