I'm trying to implement a search box that uses my CartoDb data? My current code does not work.


<link rel="stylesheet" href="http://libs.cartocdn.com/cartodb.js/v3/3.15/themes/css/cartodb.css" />
<script src="http://libs.cartocdn.com/cartodb.js/v3/3.15/cartodb.js"></script>
<div class="panel" style="height:700px">
  <div class="bar">
    <h2 class="beta">My Map</h2>
<div id="map"></div>
   <input type="Text" name="userInput" id="select-place" class="select-place"> 
   <input type="submit" value="Submit" onclick="processFormData();" />


function processFormData() {
  var input = document.getElementById("select-place").value;
  return input;

function main() {
  cartodb.createVis('map', 'https://testuser.cartodb.com/api/v2/viz/123456789/viz.json', {
   title: false,
   description: false,
   tiles_loader: false
  .done(function(vis, layers) {

  var userInput = processFormData();
  var sql = new cartodb.SQL({ user: 'testuser' });
    sql.getBounds("select * from testdb where name like ='%userInput%'").done(function(bounds) {

var subLayer = layers[1].getSubLayer(0);
 .error(function(err) {
 window.onload = main;

That code can't work, you need to put the logic on using the SQL API on the function called by the submit button (processFormData) and that createSelector call is not defined anywhere.
