          New {conversationsOpen ? 'Conversation': 'Contact'}




      <Modal show={modelOpen} onHide={closeModal}>

        {conversationsOpen ?

           <NewConversationModal  closeModal={closeModal} /> :

           <NewContactModal closeModal={closeModal} />






HERE IN THIS CODE IT IS SHOWING modalOpen is not defined
modalOpen is assigned a value but never used

so please help me how to correct this error

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Read this line closely:

const [modalOpen, setModalOpen] = useState(false)

and read this line closely:

<Modal show={modelOpen} onHide={closeModal}>

Pay attention to spelling - JavaScript certainly is.

Usually with these kinds of errors, I start with the assumption that JS is correct and I am the one that is wrong. My first instinct after finding the first line of code was to search for “modalOpen” in the code and could find no other cases - that told me something was wrong.
