[kunsane]

pragma solidity ^0.8.8

import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";

contract fundme{

uint256 public  minimumUSD = 50 ;

function fund() public payable {
require (msg.value >= minimumUSD , "Didnt send enough");
}
function getprice() public view returns(uint256) {
AggregatorV3Interface.priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);
( ,int256 price, , ,) = priceFeed.latestRoundData(); ------- UNDECLARED IDENTIFIER ERROR IN THIS LINE I DONT UNDERSTAND WHY ????
return uint256(price*1e10);

Can you share the entire code of FundMe.sol

I think priceFeed was not identified correctly in the first line of function getprice(). It should be a space instead of dot between AggregatorV3Interface and priceFeed (meaning you are setting a identifier named priceFeed which is a AggregatorV3Interface), just like the below:

AggregatorV3Interface priceFeed = AggregatorV3Interface(0x8A753747A1Fa494EC906cE90E9f37563A8AF630e);

Hope it helps.
