Grabbing can ruin a parkour replay. It's also not as simple as "grab it and try to go up". You will need to make complete contact with the wall using your hands and feet to have enough friction to be able to get up the wall.
I cannot, at the moment, provide any example of replay to show what I mean, but I hope you got a little insight on what to do.
