Trying to duplicate a Form field without success

Thanks for your reply.
I changed the input name to “tags2” like this:

<li style="width:240px; text-align:right;"><strong>[var.lang_tags]2:</strong></li>
<li style="width:400px; text-align:left;"><input name="tags2" type="text" class="upload-video-form-input" value="[var.tags]" size="38" />

Buy I can’t find what is entered into Tags2 field when searched. The mysql has a column named ‘tags’, so do you think I’d be on the right track if I added a column named ‘tags2’ in that db, and then add ‘tags2’ to this line in the search.php file:

$type_query_rows 	= 'indexer, video_id, title, title_seo, date_uploaded, user_id, video_length,  approved, public_private, description, tags, number_of_views';

I look forward to any guidance.
Much thanks
