Hi, I am trying to create a new statistic, but get the error: 'Value expression is NOT valid'
Basically, I go to the configure statistics dialogue and choose Holdem Cash Player Statistics.
Then I go to the statistics tab.
I choose new and enter a new stats name: 'pfr over vpip'
In the value expression field I enter 'cnt_pfr/cnt_vpip'
but when trying to save I get the above error. What am I missing?
