Try using this but use your own variables / values

pawn Code:

if (strcmp("/gate", cmdtext, true, 10) == 0)
    {
        if(IsPlayerInRangeOfPoint(playerid, 10, 1275.58, -1270.28, 14.32))
        {
            if(Open == false)
            {
                SendClientMessage(playerid, COLOR_LIGHTBLUE, "The gate is now opening!");
                MoveObject(gate, 1275.58, -1270.28, 4.32, 2.0);
                Open = true;
                return 1;
            }
            if(Open == true)
            {
                SendClientMessage(playerid, COLOR_LIGHTBLUE, "The gate is now closing!");
                MoveObject(gate, 1275.58, -1270.28, 14.32, 2.0);
                Open = false;
                return 1;
            }
            return 1;
        }
        else return SendClientMessage(playerid, COLOR_RED, "You are not near the impound lot!");
    }

you will need to create the variable Open so use this

pawn Code:

new bool:Open;
