Behind player? - Lajko1 - 02.03.2014

How to change this code to get position behind player?
It's for /cuff command

pawn Код:
stock GetXYInFrontOfPlayer(playerid, &Float:x, &Float:y, Float:distance)
{
    new Float:a;
    GetPlayerPos(playerid, x, y, a);
    GetPlayerFacingAngle(playerid, a);
    if (GetPlayerVehicleID(playerid))
    {
        GetVehicleZAngle(GetPlayerVehicleID(playerid), a);
    }
    //a +=0;//misschien niet bodig
    x += (distance * floatsin(-a, degrees));
    y += (distance * floatcos(-a, degrees));
}

    a -= 180.0;

if(GetXYInBehindOfPlayer(playerid,i,0.5,0.5))

Errors:

warning 213: tag mismatch
error 035: argument type mismatch (argument 3)

Actually my bad I forgot to post that also

pawn Код:
stock IsPlayerInFrontOfPlayer(playerid,targetid,Float:distance,Float:range)
{
    if(!IsPlayerConnected(playerid) || !IsPlayerConnected(targetid))return 0;
    {
        new Float:x, Float:y, Float:z;
        GetPlayerPos(targetid,x, y, z);//my pos
        GetXYInFrontOfPlayer(targetid,x,y,distance);
        if(IsPlayerInRangeOfPoint(playerid,range,x,y,z))return 1;
    }
    return 0;
}
When I changed
pawn Код:
if(GetXYInFrontOfPlayer(playerid,i,0.5,0.5))
to

pawn Код:
if(GetXYInFrontOfPlayer(playerid,i,0.5,0.5))
I received those errors

pawn Код:
warning 213: tag mismatch
error 035: argument type mismatch (argument 3)
and cmd is:

pawn Код:
if(!strcmp(cmdtext, "/cuff", true))
        {
            if(sendername[0] == '[' && sendername[1] == 'P' && sendername[2] == 'D' && sendername[3] == ']' || GetPlayerSkin(playerid) == 71)
            {
                for(new i = 0; i < MAX_PLAYERS; i++)
                {
                    if(i!=playerid)
                    {
                        if(GetXYInBehindOfPlayer(playerid,i,0.5,0.5)) // error line
                        {
                            SendClientMessage(playerid,COLOR_RED,"You cuffed a suspect");
                            SetPlayerSpecialAction(i,SPECIAL_ACTION_CUFFED);
                            SetPlayerAttachedObject(i,6,19418,6,-0.000999,0.038999,-0.016000,162.300003,-169.399963,-76.699989,0.855000,1.412998,1.711999);
                            GameTextForPlayer(i,"~r~BUSTED!!",3000,5);
                        }
                    }
                }
            }
            else
            {
                SendClientMessage(playerid,COLOR_RED,"You are not authorized to use this command!");
                return 1;
            }
            return 1;
        }
