I’m handling users within EE entries, so that variable is a field that displays text from the rich text editor. The RTE shows up just fine, it just the value that fails to show.
The form uses the third party module zoo_visitor, but it acts exactly like safecracker. I’ve changed the form to safecracker for now so you have a better time debugging.
{exp:safecracker channel="members" entry_id="{zoo_visitor_id}" error_handling="inline" rte_selector=".rte" error_delimiters="<p class="help-inline">|" include_jquery="no" return="account/edit/profile/success" class="form-horizontal" allowed_groups="5|6|7" secure_action="yes" secure_return="yes"}
<div class="control-group">
<label for="edit-introduction" class="control-label">Test</label>
<div class="controls">
<textarea id="edit-introduction" name="member-introduction" class="rte" rows="6" value="{member-introduction}"></textarea>
</div>
</div><!--/.control-group-->
<div class="form-actions">
<button type="submit" class="btn btn-success">Update</button> <a href="http://{path=account}" class="btn">Cancel</a>
</div><!--/.form-actions-->
{/exp:safecracker}
