Hello,
below i have the 2 scripts that im having problems with.
1. the javascript seems to be in a loop and not sure why.
2. sec. the ajax isnt displaying resluts sent from testData.php

testData.php itself works it pulls a set of data from the db but cant pass the the results over to display from the calling script.
any help you can give would be greatly appreciated.
thanks

HTML Code:
<div id="questiondev-wrapper">	<div id="questiondev" >	</div> </div>	
		
	<!-- ******************************************************************************* -->		
		<div id="questionButton">
			<form method="POST" name="form_questions" action="">
				<label class="error" for="saveqa" id="question_error"><p>This field is required.</p></label>
				<hr>
				<TEXTAREA NAME="saveqa" ROWS="3" COLS="50" MAXLENGTH="256" id="saveqa"></TEXTAREA>
				<BUTTON class="btn_save" id ="btn_save" NAME="btn_save">Ask</BUTTON>			  
			</form>
		</div>	
		<!--*** reload the question and answer div tag # id/ . class *******-->
			<script src="http://code.jquery.com/jquery-latest.js"></script>
	 	<script>		   
			$(document).ready(function() { 
			$('#btn_save').on('click', function() { 
			$.ajax({
				type: "POST",
				cache: false, 
				url: "testData.php",
