Copying text from browser to sketch

Hello,
Complete starter with Arduino. I want to get temperature measurement going with a thermistor. I found an example of a sketch,

so copied text from the web page and pasted into blank sketch.
I get an error message something like "stray " which I believe is something to do with the copying process.

Can anyone put me right on this?
Thanks

There's not that much code there, and yes the problem is with the embedded html tags. You'll just need to type the code into the IDE.

And, send a note to the web site author asking that the code be available as a download without the html tags embedded.

You've been hit by some fancy typography. That website substituted "smart quotes" for the regular double-quotes and Unicode EN-dash for the minus signs in lines 33, 37, and 38.

Re-type the quotes around the string constants and re-type the minus signs and it will compile.

Thanks for that - not a good start

Fairly unusual, I'd say.
