At the bottom of content, I have put two rectangular boxes ad, out of which only one shows up. Is there a restriction on showing ads per page.
Following is my code with credentials removed
<div class="bottomAds">
<div class="rectangle1">
<script type="text/javascript"><!--
google_ad_client = "ca-pub-********";
/* Rectangle-1 */
google_ad_slot = "******";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</div>
<div class="rectangle2">
<script type="text/javascript"><!--
google_ad_client = "ca-pub-*******";
/* Medium-Rectangle */
google_ad_slot = "******";
google_ad_width = 300;
google_ad_height = 250;
//-->
</script>
