Resolving the Value Not Received from HTML Error in Google Apps Script

When developing web applications using Google Apps Script, you may encounter issues with form submissions, especially when data seems to go missing. This can lead to frustrating errors, such as TypeError: Cannot read property 'toString' of undefined. If you're currently facing this error, you are not alone. This guide will explore the cause of this problem and provide an effective solution to ensure your additional fields are captured correctly.

Understanding the Problem

In your application, you might have set up an HTML form intended to gather user inputs, such as names and contact numbers. However, you may notice that certain fields do not seem to be sending their values properly to your JavaScript functions.

Steps to Fix the Issue

Identify the Input Elements: Locate all the input fields in your HTML form that capture user inputs.

Add name Attributes: Ensure that each input field has a properly defined name attribute that matches the expected parameter name in your script.

Implement this small change, and not only should the error disappear, but you'll also find that your application runs more efficiently and effectively captures all necessary data.
