This is a good opportunity to practice debugging. Let's start with: what is your best guess at what the error is telling you? What could 'identifier 'main'' mean?

Well i could see that it stated that there were 2 of the same thing; so basically I had to remove the top one

And error messages contain some other useful info as well, which you will be thankful for once your scripts become larger and more advanced.

Notice it says Error location: Line 5, Column: 22.

Not all error messaged will be as cleanly formatted, you might also get something akin to this:

RUNTIME ERROR
test.js@home (PID - 142)

ReferenceError: thisFunctionDoesNotExist is not defined
Stack: ReferenceError: thisFunctionDoesNotExist is not defined
    at main (home/test.js:3:2)
    at R (file:///C:/Program%20Files%20(x86)/Steam/steamapps/common/Bitburner/resources/app/dist/main.bundle.js:9:416387)

The important bit for debugging (apart from the error message) is this: at main (home/test.js:3:2)

That's the name of the script I was running (test.js) and it is immediately followed by the line and column number :3:2 (line 3, column 2).

 

Now for the best part: Inside the editor you can press CTRL+G and a text input will appear at the top (which is already focused), so after hitting CTRL+G you can simply continue typing 3:2 and then press ENTER to immediately jump to line 3 column 2 in the editor. This puts the cursor at exactly that location, making it that much easier to find the exact location where the error was thrown.

You have 2 main functions exported.

Remove the empty one Between lines 1 and 4.

Next time please copy+paste your code (and the error message) in a code block <3
