What's wrong with my sliding door? on 2003 Honda Odyssey

My door will not close. I have to keep opening it and when It starts to close I have to guide it and lean on it to get it to close all the way and sometimes that is not working. When I push the button or pull the handle for it to close automatically it starts to close and when it's all most closed it beeps and reopens.
