Is this code right to check if the user is verified or not?

    <form class="myForm" style="max-width: 200px; margin: auto;">
        <p>Enter your first name:</p>
        <input id="firsName" style="margin-bottom: 20px; margin-top: 2px;" type="text" 
        placeholder="F_Name">
        <p>Enter your second name:</p>
        <input id="secondName" style="margin-bottom: 20px; margin-top: 2px;" type="text" 
        placeholder="S_Name"><br>
        <p>Enter your email:</p>
        <input id="email" style="margin-bottom: 20px; margin-top: 2px;" type="email" 
        placeholder="Email: ">
        <p>Enter your password:</p>
        <input id="password" style="margin-bottom: 20px; margin-top: 2px;" type="password" 
        placeholder="Password: "><br>
        <p><input id="checkbox" type="checkbox">I am not Robot</p>

        <input onclick= "formSubmission(firsName, secondName, email, password, checkbox)" 
        type="submit" value="Submit">
    </form>

In this code i took user`s some info as input and wanted to check if the user is verified or not, i made html-form and in form i also made one input of type checkbox as 'I'm not robot'. and made a small function in which i set the condition that if the checkbox have value then return 'user is verified' else return 'user is not verified'. This whole code worked well but except the part of checking the user verification that if the user is verified or not! Now Please tell me where is mistake?
