uint256 linkAmt = amount * 10**18;

[login to view URL](_msgSender(), address(this), linkAmt);

}

function approveTransfer(uint256 amount) external returns(string memory) {

uint256 approveAmt = amount * 10**18;

userlinkbalance = [login to view URL](_msgSender());

[login to view URL](address(this),approveAmt);

// [login to view URL](_msgSender(), 1000);

// linkAllowance = [login to view URL](_msgSender());

// [login to view URL](_msgSender(), amount);

link._approve(_msgSender(), 1000);
