@deepak2301 This is not passing the first condition of the fund function, either your price feed address is wrong or there might be an issue with the getConversionRate function. It would be better if you leave your fund me repository link.

And for this <unrecognized-selector> you should first clean your artifacts folder by running this command npx hardhat clean and then recompile npx hardhat compile and now add the newly generated abi to your frontend file. Do this whenever you update every single character inside your smart contracts to get the accurate abi for frontend.

I did hardhat clean and copied new abi in fronted file still same is showing

and here's my fundme repo link :- https://github.com/deepak2301/hardhat-FundMe

error fixed i just removed fund() from fallback and receive() in FundMe.sol
