This seems really silly but I can't get a simple form to work. Here's my code:

```
<section class="row-fluid"> <!-- search-by-text -->       
     <div class="span8 offset1"> <!-- search by Name input field-->
            <form class="form-horizontal" role="form">
            <div class="form-group form-group-lg">
              <?php echo form_open('../main_controller/gsd_search'); ?>
              <label class="col-sm-2 control-label" for="formGroupInputLarge">Search by Name</label>
              <div class="col-sm-8">
                <input class="input input-lg input-block-level" type="text" id="search_text" placeholder="Enter name then click 'Search'">
              </div>
             <div class="col-sm-2"><!-- search button -->
                <?php echo form_submit('submit', 'Search by Name', "class='btn btn-large btn-success'"); ?>
                <?php echo form_close(); ?>
              </div> <!-- end search button -->         
                </div>
        </form>
    </div> <!-- end input field and button -->    

```

When I click on the 'submit' button the URL has 

> 
> ?submit=Search+by+Name
> 
> 
> 

attached to it.

Any help with this stupidity would be greatly apreciated.
