Arduino library called TimedAction

When I use the example listed in the documentation for TimedAction it does not compile. Shouldn't it compile when I copy exactly what the sample is? Where is the proper forum for asking this question?
Thx anyone

DON’T start multiple Threads about the same project. I have asked the Moderator to merge them.

Post a link to the documentation you are referring to.

Post the code you have tried.
And please use the code button </> so your code looks like this and is easy to copy to a text editor

Post the error messages that the compiler produced.
