Try it like this..

pawn Код:

new PlayerText3D:Recon;

Just for one class:

pawn Код:

Recon = CreatePlayer3DTextLabel(playerid,"Recon",0x000FFFFF,30.0,40.0,50.0,40.0,0);
Attach3DTextLabelToPlayer(Recon, playerid, 0.0, 0.0, 0.7);
IsRecon[playerid] = 1;

Just removed 'PlayerText3D:Recon' from the line above and simply put 'Recon' try that under all of the lines you have used 'PlayerText3D:Var'.
