Okay, I shoulden't have that trailing "*"?

It wasn't my intention, but I can see that's what happened.

So, that part seemed to work. But obviously not compared to what happened above.

And again something is completely wrong, I see.

As I said, I am far from confident with the syntax/mecanism here. So I
would really appreciate some more explicit help. I have tried to
modify the chat by removing the trailing "*" or by putting the
expressions into double quotes - but with no luck.
Again, what is going on in the console is exactely what I wrote above.
What would then be tbe correct chat?
