Backing up my contacts and appointments with Google

[radar369]

I know this probably doesn't belong here, but I figured since other people are creating threads that isn't helping anybody (other than passing time) I would create a thread that would.........well.......@ least help me (and if not just me than other people too)!

Now that that's out the way............HOW IN THE HELL do you sync contacts and appointments with Google?! I went to Googles website but it doesn't work for me! Do I have to be on a stock rom for it to work! Can someone give me detailed instructions on how to sync them successfully because I tried like a millions times with no luck?!?!?!?!
