I have a contenteditable div, that I need to simply be a textarea, however once I change it, it no longer functions correctly for posting information. Here is the code (not all of it just a little part)

Code:
<div id="submit_form">
<ul class="col">
 <li><label for="tool_name">Tool Name</label></li>
 <li><input type="text" name="tool_name" id="tool_name"/></li>

 <li><label for="tool_description">Description</label></li>
 <li><div class="text lines_3" name="tool_description" id="tool_description" contenteditable></div></li>
What is the best solution?
