Code not working

Hello,

I am not a familiar with codes, and the company I purchased my theme from won’t help me… Can someone please help me figure out how to change this code so it works?

<div class="our-form">
    <div class="row">
        <div class="col-sm-6 col-md-6">
            <div class="form-group">
                [text* name class:form-control placeholder "Name"]
                <div class="input-bottom-line"></div>
            </div>
        </div>
        <div class="col-md-6 col-sm-6">
            <div class="form-group">
                [email* email class:form-control placeholder "Eamil"]
                <div class="input-bottom-line"></div>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="col-md-6 col-sm-6">
            <div class="form-group">
                [text* address class:form-control placeholder "Address"]
                <div class="input-bottom-line"></div>
            </div>
        </div>
        <div class="col-md-6 col-sm-6">
            <div class="form-group">
                [tel* phone class:form-control placeholder "Phone"]
                <div class="input-bottom-line"></div>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="col-sm-12 col-md-12">
            <div class="form-group">
                [textarea message class:form-control placeholder "Message"]
                <div class="input-bottom-line"></div>
            </div>
        </div>
    </div>
    <button type="submit" class="red-button bgcolor">
        [submit "submit"]
    </button>
</div>

My website is https://www.garagedoormadisonwi.com and the error I am seeing is “Unavailable names (name) are used for form controls.”

Thanks!
