If it's ever not conveniently formatted to use with sscanf, you could always do something like:

pawn Code:

new tmpstr[80]; 

format(tmpstr, sizeof(tmpstr), "PLIST_%i_USERID", countPlayers);
SetPVarInt(playerid, tmpstr, get_players_id);

That would be inside your iteration. How do you use it?

pawn Code:

new tmpstr[80], get_player_id; 

format(tmpstr, sizeof(tmpstr), "PLIST_%i_USERID", listitem);
get_player_id = GetPVarInt(playerid, tmpstr);

Inside your OnDialogResponse. Delete it after.

We're using the listitem the player would be at in OnDialogResponse and setting their ID through the PVar.

listitems start at 0 and as does your countPlayers variable.

It's pretty simple and self explanatory but if you don't understand, let me know and I'll explain further.
