Error −41003 Help

[monicasenese]

Hey all, I am trying to write to an Excel file, read said data, and then graph the data in the excel file as well. Currently I am just trying to graph arbitrary random numbers before I actually code in my real data, but even that isn't working. I keep getting Error -41003 right after the Save Report to File VI, and I have no idea how to fix this. Below attached is the VI I am trying to execute. Please help if you have seen such an error. Thank you.

Here is the code:

That error code means the file is already open.  Make sure it's not open in another editor or application on your computer before you try to write to it programmatically.

If you right-click the error code in the error cluster you will see a pop-up that has "Explain Error" at the top.  Select that to see what the error or warning means.  I don't think 41003 is even a LabVIEW error.  It probably got passed through from your OS.

If you need further help it's a good idea to back-save (use Save for Previous Version...) to 2018 or so. That way more of us can see your code.  I'm using 2019 for example.
