Players Report: AllinEquity Groups

[FilS2BotS]

I wish to have a reports Players that could display a Column with different groups of hands based on a Allin Equity window...
I did built this Column named "equity_grp": if[tourney_hand_player_statistics.val_equity*100<20, 1, if[tourney_hand_player_statistics.val_equity*100<30, 2, if[tourney_hand_player_statistics.val_equity*100<45, 3, if[tourney_hand_player_statistics.val_equity*100<55, 4, if[tourney_hand_player_statistics.val_equity*100<70, 5, if[tourney_hand_player_statistics.val_equity*100<80, 6, if[tourney_hand_player_statistics.val_equity*100<100, 7, if[tourney_hand_player_statistics.val_equity*100=100, 8, 0]]]]]]]]
Then i did built this Stats names "Equity": Expression: equity_grp
And i had for plan to do the Format Expression like this: if(this = 1, 'a', if(this = 2, 'b', if(this = 3, 'c', if(this = 4, 'd', if(this = 5, 'e', if(this = 6, 'f', if(this = 7, 'g', if(this = 8, 'h', 'i'))))))))

So my problem is that the Format Expression is not valid (looks like it ithe "if" that bloq it)... And i'm not sur that "tourney_hand_player_statistics.val_equity" is the expression that could do what i expect to do...
Thank You to help me.

That sort of thing should work, but I'm afraid I don't have time right now to experiment with this.
What I would do first is take out the format expression altogether and just display the value of your column and see if that works.
If it does, try adding the IF statements in one at a time to start with and see if you can get it to work with a single case. You could use "insert" to make sure each part is constructed correctly - it could be some simple construction error.
If you can't get it working please post back and one of us will look into it when we have a little time.
