TypeError: Member "store" not found or not visible after argument-dependent lookup in contract SimpleStorage.

Getting the error:

from solidity:
TypeError: Member "store" not found or not visible after argument-dependent lookup in contract SimpleStorage.
--> contracts/StorageFactory.sol:20:9:
|
20 | simpleStorageArray[_simpleStorageIndex].store(_simpleStorageNumber);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^**

from the code:

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;

import "./SimpleStorage.sol";

contract StorageFactory {

SimpleStorage[] public simpleStorageArray;

function createSimpleStorageContract() public {
    SimpleStorage simpleStorage = new SimpleStorage();
    simpleStorageArray.push(simpleStorage);
}

function sfStore(uint256 _simpleStorageIndex, uint256 _simpleStorageNumber) public {
    simpleStorageArray[_simpleStorageIndex].store(_simpleStorageNumber);
}

function sfGet(uint256 _simpleStorageIndex) public view returns (uint256) {
    return simpleStorageArray[_simpleStorageIndex].retrieve();
}

}

Does anyone know why this is?

can you also post the code for simpleStorage contract?

[jacobhay2626]

yes of course, // SPDX-License-Identifier: MIT pragma solidity 0.8.8; // pragma solidity ^0.8.0; // pragma solidity >=0.8.0 <0.9.0; contract SimpleStorage { uint256 FavNumber; struct People { uint256 FavNumber; string name; } People[] public newperson; mapping(string => uint256) public nameToFavNumber; function Store(uint256 _FavNumber) public{ FavNumber = _FavNumber; } function retrieve() public view returns (uint256){ return FavNumber; } function addPerson(string memory _name, uint256 _FavNumber) public { newperson.push(People(_FavNumber, _name)); nameToFavNumber[_name] = _FavNumber; } }

Jacob,

it's showing you that error because in your simpleStorage contract, you have written function name as Store (with a capital S) and whenever you are calling this function in your sotrageFactory you are calling it as store (using lowercase S here).

Therefore, just change the function name from Store to store in your simpleStorage contract and your error will be solved.

Let me know if it helped you.. :)

Yes Thank you that has fixed the issue, just getting started with coding but already abundantly clear that the little details matter a lot

You got this, I have made the same error many time haha. Make sure to label your question as answered.

Good luck:)
