There are a few possible reasons why you might not be able to get the value of an input field in JavaScript. Here are a few things to check:

  1. Make sure that you are selecting the correct element: Make sure that you are selecting the right input field using the correct DOM element or element ID. You can use the document.getElementById method to select an element by its ID, or you can use a DOM query method such as document.querySelector or document.querySelectorAll to select elements using a CSS selector.
  2. Make sure that the input field has a value: If the input field is empty, you will not be able to get its value. Make sure that the input field has a value before trying to retrieve it.
  3. Check for syntax errors: Make sure that you are using the correct syntax to retrieve the value of the input field. The correct syntax is inputField.value.
  4. Make sure that the input field is in the correct state: If the input field is disabled or hidden, you will not be able to get its value. Make sure that the input field is in the correct state (e.g. enabled and visible) before trying to retrieve its value.
