What is a Script Error in QuickBooks Desktop?

Script errors are generally related to Internet Explorer, and QuickBooks uses Internet Explorer’s settings to connect with the Internet. If JavaScript or VB Script has installation errors or if, for some reason, Internet Explorer is unable to execute these scripting languages, then a script error emerges in QuickBooks Desktop and displays an error message “QuickBooks Script Error Unable To Get Property Length of Undefined or Null Reference.” However, resolving script errors in QuickBooks does not require immense troubleshooting and can be rectified by resetting Internet Explorer’s settings and implementing a few essential troubleshooting solutions.

Script Error Message: An error has occurred on the script of this page Line: 7 Char: 561
