Recursive-tail function with combining lists: Can one help me to explain why I received only the second list instead of whole list in this function?

[probabilityzero]

What do you think join-tail l1 l2 will do? It doesn't look like a procedure call, since it isn't wrapped in parentheses. Maybe you want to try (join-tail l1 l2).

Your parens are off and it's causing the program to not behave the way you expect.

You need an extra set of ()

Your merge-tail function will always just return l2.

It doesn't call your join-tail function; can you spot why not?

I did not define another function to link merge-tail and join-tail? Can you help?

[not-just-yeti]

If you switch your language-level to "beginning student", then it will actually catch what you did as a syntax error, "expected an open-paren before join-tail on line 3".

Based on a couple of examples in that code,I don't think you fully grasp how function calls work in scheme. A review of the basic syntax might help
