About the Debug Tools
The Microsoft Script Editor provides a full set of debugging tools for testing and troubleshooting HTML pages and scripts. These tools are not installed in a typical Office installation. If the debug tools are not installed, you will find the Install Web Debugging command on the Debug menu. Click this command to install the debug tools. You may be prompted to restart the Microsoft Script Editor to make the debug tools available.
For details about using the debug tools in the Microsoft Script Editor, see Inspecting Your Program.
