Variable in another variable

Hello, I want write to file such data - [tennis_player{sel_index}_points_won] , I am trying to indicate current selection index in variable but i get text instead of value : tennis_player{2}_points_won , please help

Hi
If your conditions have defined the current selection you can use text: [sel_index] [tennis_player_points_won]
for example:
write to file
text:  [sel_index] [tennis_player_points_won]
condition: selections index is equal to 2

oh great, thanks
