return uint256 (answer * 10000000000); // 1**10 == 10000000000
}

// its the only line of code in my contract that doesn't work and it says

@RahaPapa try this

return uint256(answer * 10000000000); // 1**10 == 10000000000
}

There is not much to be comprehended here and can essentially be just one problem, which is type conversion.
We should be converting the (answer * 100....000) into uint256 type as we are returning that type. Copy the code below:

return uint256(answer * 10000000000); // 1**10 == 10000000000
}

Hope this helped

@RahaPapa @krakxn when you write uint256, there should not be any space between it, uint256 () is not correct, it should be uint256()

Oh yes - that was suppposed to be the only change and I totally forgot haha. I fixed it now.

@RahaPapa I am struggling to understand the issue. could you reformat your question following the how to ask a question guide?

[RahaPapa]

@ali-thegilfoyle thank you for the How to ask question guide! I figured out the problem myself. it was the the line before that had athe problem. I mixed up words answer and price after int256. Correct line of code is:

(, int256 answer, , , ) = priceFeed.latestRoundData();
