Hello, this change looks good, I have just minor comments about
improving names of variables.

I would suggest to call this variable "select" or something like that.
Name "pwr" is too generic and does not express the fact that is stores
token select id.

Here variable "val" is also too generic. The real meaning of this
variable is tokenid. So I would suggest to use this name as it is used
in other places in this file for storing token id.
