Can't compile fhe contract on Remix cause of lint error

I wrote an fhe contract and on this particular line euint256 points = FHE.select(FHE.eq(number1, playerNumbers[0]), FHE.add(points, FHE.asEuint256(10)), points), i get this lint error - TypeError: Member "add" not found or not visible after argument-dependent lookup in type(library FHE).

My editor of choice is Remix IDE. Getting the same error on my vscode

Hi @Beardless ! The error you encountered is normal. FHE.add does not support euint256. The largest supported euint is euint128.

@AlexB
Implemented the changes and the lint error was gone but i get this new lint error Member "select" not found or not visible after argument-dependent lookup in type(library FHE). in this line string memory topWinnerUsername = FHE.select(FHE.gt(totalPoints, _topWinner.points), username, _topWinner.name);

What is the type of username and _topWinner.name ?

They’re both of type strings. In the next line, I have this code address topWinnerAddress = FHE.select(FHE.gt(totalPoints, _topWinner.points), msg.sender, _topWinner.userAddress); and i still get the same lint error. topWinnerAddress and _topWinner.userAddress are both of type address
