Problem with programme

You may recall that some days ago I asked for help to solve a problem relating to a ''Temperature switch '' This is project 10.27 in
Chapter 10 of the Publication ''Franzis Tutorial for Arduino.

It turns out that line 17 of the Programme on Page 206 is superfluous
Additionally line 18 uses what looks like a figure 1 without the horizontal stroke when in fact it is a lower case l
I quote ''Serial.println(Uf)''

It would be more help if in any future reprint of the book a different font was adopted

As I found the help I required outside this forum I shall not be troubling you with my requirements any further

world-record flounce?

Fine. Go and find your answers in horrible books then, were you can't copy-and-paste, nor apparently tell the difference between println and print1n.

Oh, and "BA (Hons) Open" in what? Not reading, that's for sure. You're not a "Media Studies" student are you? One of those oiks that spends all day watching daytime TV at the expense of us hard-working taxpayers...?
