I'm only on the second example in the beginners guide pdf, and i can't get it to work (it tells me btn0 isn't defined) I can't see what i did wrong.
Also in the search and replace picture it says it replaced 6 things, but in my editor it only replaced 4
Yes, you are right, in the explation for modifying MyFirstProgram, the declaration of btn0 is missing.
You must change line 12 to

There is no need to declare other buttons.
Nevertheless the final source code of SecondProgram is OK.
It will be corrected in the next update, also for the number of replacements.
Thank you for reporting it.
Sorry for answering somewhat late, but I was absent from home during two days.
Best regards.
