Hi can anyone help me?

I can’t fix these problems

Would you mind showing your code? I believe it’s complaining about you passing in FString as an argument but need to see your code to better see why.

I’m curious if Guess==HiddenWord isn’t comparing two different types. But looking at this on my phone is driving me nuts. So this is more to give you something to test until I can get to a place to see it better. When in doubt, commenting out and retesting from a known point is an awesome way to make progress on what exactly is causing it. Then you don’t risk losing it, but can test moving parts separately.

I’ve edited your post to use a code block. Please see how that is done and please use it in the future.

Your issue is due to missing * for printing the hidden word using formatting in your block for if (Lives <= 0)
