Lesson 4: I am getting Gas Estimation error after clicking the Fund button

[amisha2003]

I am getting this error after clicking the Fund button
Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Returned error: {"jsonrpc":"2.0","error":"execution reverted","id":4815795008038525}

@amisha2003 This code looks correct, make sure you sent the funds (msg.value) while clicking the fund function in the remix.

I also encountered this problem, you can try to set the GAS LIMIT to empty。

You got this error Right!

This error occurs because you dont have Testnet Eth in your account. Go to https://faucets.chain.link/sepolia and get some faucets and try again.
