Ladder Escape Help!

I need help with the mount! I get something really weird. After I bring the yoyo behind the strings it tels me to curl my finger in the out and all that. I do that and then it says to bring my thumb and find a certain spot and bring it up. I don’t know where that is all i see is one spot so i put my thumb their and it totally looks wrong. I don’t know how to do it! I looked at everynsingle video and none of them help!

Did you look at this one?

At around 0:42
You just have to open up the loop on your throwhand pointer with your thumb after you curl your pointer in.

OMG THANK YOU SO MUCH! I did look at that video but i didnt get it i kept doing osmthing wrong and i got it. I can finally do the trick. Thanks!!!
