I'll show examples the reports that I originally ran (and why they are or are not what I am after).
In this first report, the filter is:
#Player# LIKE 'Player0%' OR #Player# LIKE 'Player1%'
That's fine and pretty much as wanted.
Next I want the same information subtotaled by position, for just these players, but not grouped by these players. So I remove Player from the Report stats, but leave player in the filter, but get the same report (just without player names)..
So instead if I try putting the filter in by the new stat - I replace:
#Player# LIKE 'Player0%' OR #Player# LIKE 'Player1%'
with
str_player_name_no_group LIKE 'Player0%' OR str_player_name_no_group LIKE 'Player1%'
That then gives me the error message you saw in my previous post:
