My problem is this little guy in your /pickup command.

pawn Code:

GetObjectPos(PlayerInfo[i][pWeedPlante], wX, wY, wZ);

Well you mis-spelled Plant which should have given you an error. Also, you put PlayerInfo[i] when later you use playerid. So it should be like this.

pawn Code:

GetObjectPos(PlayerInfo[playerid][pWeedPlant], wX, wY, wZ);

Also, under your pickup command you have this.

pawn Code:

if(PlayerToPoint(6, playerid, wX, wY, wZ))
{
  {

There is no need for two opening brackets. I think the compiler will ignore it, but it is unnecessary.
