When columns do not exist you get an 'Invalid Value Expression' error so that would mean you haven't created those columns in the 'Columns' section. Also bear in mind that you cannot create new statistics just by changing column names - columns contain expressions and those need to be created/edited too so they count the situation you want. Go to 'Configure -> Statistics', select the 'Columns' tab and look at the '
cnt_p_3bet_t_cbet_def_action_call' column. Here you will see code in the 'Expression' box and these custom columns are what you need to create first before using the names of your custom columns in the value expression of a custom statistic. Please read to the guides I linked you to in
this post and the example I posted
here so you can better understand how this works.
