Stack too deep, try removing local variables. _tOwned[sender] = _tOwned[sender].sub(tAmount);

Question

I need help, i don't understand this Error...

Code:

function _transferFromExcluded(address sender, address recipient, uint256 tAmount, bool lottery, bool updateWinner) private {
    uint256 currentRate =  _getRate();
(uint256 rAmount, uint256 rTransferAmount, uint256 rFee, uint256 tTransferAmount, uint256 tFee, uint256 tBurn) = _getValues(tAmount);
uint256 rBurn =  tBurn.mul(currentRate);

_tOwned[sender] = _tOwned[sender].sub(tAmount);
_rOwned[sender] = _rOwned[sender].sub(rAmount);
_rOwned[recipient] = _rOwned[recipient].add(rTransferAmount);   
_reflectFee(rFee, rBurn, tFee, tBurn);
if (lottery == true && updateWinner == true) {
    uint winnings = getTotalWon(recipient);
    uint256 _totalWin = winnings.add(tTransferAmount);
    updateWinnings(recipient, tTransferAmount, _totalWin);
} 
emit Transfer(sender, recipient, tTransferAmount);

}

Erro:
