Dear James,

First of all, thank you for your valued javaScripts for AI. However, I found this error when I ran the script. Would you mind to suggest me how to fix it?

Best regards,
Krittima

Hello - from the screenshot it looks like you are running the script without an active document open. Try opening the test document: "docs/test/Ilustrator-script-tests.ai" and then run the script.
