Additional Headers Issue

Here’s my issue “There are invalid mail header fields.”

Here’s the mail settings:
Reply to: [your-email]

Here’s the form settings:
<div class=”row video-main-contact”>
<div class=”col-md-12″>
[textarea your-message class:dm_main_text_7 placeholder “Please write your message here…”]
</div>
<div class=”video-form-bottom-part”>
<div class=”col-md-3 col-xs-12″>
[text your-name class:dm_main_name_7 placeholder "Name"]
</div>
<div class=”col-md-3 col-xs-12″>
[text your-subject class:dm_main_sub_7 placeholder "Subject"]
</div>
