I am taking a course and one of our projects is to create a form. Forgive me as I am a total newbie here.
The instructor is asking that the form action attribute="#" and the method="post"
When I use the # I just get an error 
<form name="my-form" action='#' method='post'>
    <fieldset>
        <legend>Sign Up Here</legend>
        <div class="form-box">
            <label for="username">Username</label>
            <input type="text" id="username" name="username" tabindex="1" placeholder="Username">
        </div>
        <div class="form-box">
            <label for="email">Email</label>
            <input type="email" id="email" name="email" tabindex="2" placeholder="Email" required>
        </div>
        <div class="form-box">
            <label for="phone-number">Phone</label>
            <input type="text" id="phone-number" name="phone-number" tabindex="3" placeholder="Phone" required>
        </div>
        <div class="form-box">
            <label for="password">Password</label>
            <input type="password" id="password" name="pass" tabindex="4" placeholder="Password" required>
        </div>
        <div id="message">
            <h6>Password must contain the following:</h6>
            <p id="letter" class="invalid">A <b>lowercase</b> letter</p>

            <input type="password" id="password-confirm" name="password-confirm" tabindex="5" placeholder="Confirm Password" required>
        </div>
        <div class="form-box">

        <div class="form-box">

        </div>
    </fieldset>
</form>
