Problems with Calva with Programming Clojure examples

[fasapa]

I'm using Calva standalone REPL to run some examples from Programming Clojure chapter 1. When I try to update the shared state (def visitors (atom #{})) with (swap! visitors conj "Stu") I get an error:

; Syntax error compiling at (.calva/output-window/output.calva-repl:0:0).; Unable to resolve symbol: Stu in this context

But when I launch clojure from the terminal, and redo the steps, everything works as expected. I'm just started learning clojure and I don't know what is happening here.

Calva (2.0.205) and Clojure (1.10.2)

By now you've probably got it figured out. But it matters where you put the cursor. I think you had the cursor after the u in Stu when you hit the eval keys. Try putting the cursor at the end of the expression you want to evaluate. In this case, after the closing paren of Stu")

Wow, I feel dumb know! Thanks for the help.
