Can we please have a clue as to the problem that you are having ?

There are several long lines that you have used a line feed to wrap the text. This is causing an unterminated line error. Remove the line feeds so the text is all on one line or use \ (backslash) where you want to wrap the line to tell the compiler that the text continues on the next line.

Are those functions in the dht library that you are using? Are they spelled right?

Please read the how to use this forum-please read sticky to see how to properly post code and some advice on how to ask an effective question. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code.

The warning you can ignore for now.
