[Scriptissue]

I tried to make a script that allows to slap, but it doesn't work, first I tired many things but it didn't work, I just can't solve it.

PHP код:

C:\Documents and Settings\My Documents\Downloads\samp03bsvr_R2_win32\gamemodes\RP.pwn(634) : error 017: undefined symbol "ReturnUser"
Pawn compiler 3.2.3664              Copyright (c) 1997-2006, ITB CompuPhase
1 Error. 


PHP код:

    if(strcmp(cmd, "/slap", true) == 0)
    {
        if(IsPlayerConnected(playerid))
            tmp = strtok(cmdtext, idx);
            if(!strlen(tmp))
        SendClientMessage(playerid, 0xFF4646FF, "USAGE: /slap [playerid/PartOfName]");
                return 1;
            }
   new play;
 line 634:   play = ReturnUser(tmp);
   new Float:slx, Float:sly, Float:slz;
   GetPlayerPos(play, slx, sly, slz);
   SetPlayerPos(play, slx, sly, slz+5);
   PlayerPlaySound(play, 1130, slx, sly, slz+5);
return 1;
    }
