Question

I had built a staking contract but while testing the staking it's throwing The transaction has been reverted to the initial state. Note: The called function should be payable if you send value and the value you send should be less than your current balance. Debug the transaction to get more information. The transaction has been reverted to the initial state. Note: The called function should be payable if you send value and the value you send should be less than your current balance. Debug the transaction to get more information. this error. My code is `

function startGame(address secondPlayer, string memory phrase, uint _amount) external { 

require(token.balanceOf(msg.sender) >= _amount); uint _stakedAmountChallenger = stakeZug(_amount);
    uint secret =uint(keccak256(abi.encodePacked(phrase)));

matchLists.push(matchUps(matchStatus.Start,msg.sender,secondPlayer,_stakedAmountChallenger,0,_stakedAmountChallenger,secret,false));
                uint gameNumber = matchLists.length -1;
                isValid[gameNumber] = true;
                emit challengeInitiator(msg.sender, secondPlayer, false, gameNumber);
            }
