SetPlayerCheckpoint is wrong. I think you gave it angle parameter as well

pawn Код:

SetPlayerCheckpoint(playerid, 115,2699.4993,-2226.0491,10);

For any loose indentation add

pawn Код:

#pragma tabsize 0

at top of your code.

Also, make sure that /dropoff code is inside OnPlayerCoommandText

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if(strcmp(cmdtext, "/dropcar", true) == 0)
    {
          SendClientMessage(playerid, 0xFFFFFFFF, "{FF0000}SERVER: Drop The Car Off At The Checkpoint!");
          SetPlayerCheckpoint(playerid, 115,2699.4993,-2226.0491,10);
          return 1;
    }
    return 0;
}
