Using the Browser's Developer Tools to find Errors

Every modern web browser includes a function called "developer tools".
These tools help us find out more about the underlying page code and functions.

In the case of Buying Buddy it provides a very useful way for debugging JavaScript that isn't working as expected.

This article provides instructions on how to access and view the messages in this tool.

Follow the instructions below to discover potential problems.

If you need assistance from us, then send us a screenshot of these error messages in your help ticket, so that we can more quickly resolve issues.
