Basically, from the root of the navigation controller, a table view, I build a URL string that contains the information i want to display on the new tableView. in the new table view i use the URL for an NSURL request. My code gives me no error but crashes, right after the NSLog: made cells. help before i kill myself. sorry should all be together but copy pasting code obviously doesn’t work well.

Your trips array is being autoreleased – try retaining it and see if you still get the error.
