**ActionScriptError** occurs **when the script entered in the settings causes an error**. This error usually falls into the following two cases:

1. It worked fine at first, but **the site structure or loading method changed and the code was neutralized**
2. Possibility that the code was written incorrectly from the start (selector error, syntax issues, etc.)

* **If it is code you wrote yourself**, please check whether the site's structure or button positions have changed recently.
* **If it is code created using an AI tool**, try regenerating it or check the click targets and conditional logic.
* **For scripts provided by Listly as a paid service, within 5 days from delivery** if a problem occurs, one free revision is available. → After that, modifications due to site changes **will require a separate request and fee** can be done.
