Сделал, но выдает ошибку, подскажите куда копать:

(index):552 Uncaught TypeError: document.getElementById(...).style is not a function

div id='banner' style='z-index:1000; position: fixed; bottom:0px; center:0px; width: 100%; height: 20%; display: none;'><table border=1 cellspacing=0 cellpadding=0 width=240 style='background-color:#ffffff'><tr><td align=center>
<a style='float:right; margin-right: 8%;' href='#' onclick='document.getElementById("banner").style.display="none"'><b>Х</b></a> <br>

<div id="bclk481"></div><script type="text/javascript">
(function(w){var l = function() {
  var n = document.getElementsByTagName("script")[0],
  s = document.createElement("script"),
  ins = function () { n.parentNode.insertBefore(s, n); };
  s.type = "text/javascript";
  s.async = true;
  s.src = "//url.com/next.html?xFEU3ChReGhEc44xASUFNX66XNhcMK7odHhEARUg";
  ins();
};
l();
})(window);</script>

</td></tr></table></div>

<script type="text/javascript">
setTimeout(function() 
{document.getElementById("banner").style("display", "inline");}, 5000);
</script>
