I am sorryyy... My mistake i did'nt see that you had attached the file ...my mistake..anyhow i have solved your problem. so i am going to explain....
open your file...select hand... go to Subdiv Serfaces > Standard Mode.
then select your hand again...right click > Vertex.
Right click again > Display Level 1. It will show the vertices...but here is another problem in your file... that is the vertices of the middle part of your fingers are missing. they are actually somehow sort of hidden. so the solution is
select the top vertices of each finger and move them a bit backwards. and the vertices of the middle part of the finger will show up. from that on...you can follow the document. ;o)
Cheers.
