JavaScript Error: 'callCHATGPT is not defined' - How to Fix

This error message indicates that there is an issue with the 'callCHATGPT' function not being defined in the JavaScript code. The onclick event of a button in the HTML file is trying to call this function, but it cannot find it.

To resolve this error, ensure that the 'callCHATGPT' function is properly defined in the JavaScript file and that it is loaded before the HTML file. Check for any typos or syntax errors in the function name and make sure it is accessible from the scope of the onclick event.
