if you are viewing the ad in a page on your computer, you may only see one ad because Adsense only fills one space with a public service ad. It leaves all the rest blank.
When you upload to the website, it will fill as many ad blocks as it can find advertisers for - though it may take the adsense robot a couple of days or more to process your page and find the right ads. If there isn't much ad copy available, it may only fill one block.
So, upload the page(s) and give it a few days and see what happens.
But make sure you copy all the code from the Adsense website for each ad each time. That is, your html should look like this if you have 3 ads on the page:
Content, content, content
<script type="text/javascript"><!--
google_ad_client = "pub-blahblahblah";
google_ad_width = blah;
google_ad_height = blah;
google_ad_format = "blah";
google_ad_type = "blah";
google_ad_channel ="blah";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

<script type="text/javascript"><!--

google_ad_type = "blah";
google_ad_channel ="blah";
//--></script>

But reading your comments, it sounds like you may be adjusting the ad code by changing "google_ad_width, google_ad_height" parameters.
Do what 21_blue said and make sure you have code copied from Google Adsense for three separate ads.
Some have suggested that it takes time for Google's servers to send enough ads there. I've also seen another answer (apparently from Google itself) and according to it, when there are not too many ads for the keywords on your page - and you might not have too many of them if you have just started - there will not be enough ads for two different ad blocks.
Anyway, what I did was that I removed my first ad completely, then placed the second ad, and then the first one again. That seems to have done the trick for me.
