Unable to put more than one ad unit on the page

I keep trying to add more than one ad unit but only one add unit actually shows up on the page, is anyone else having difficulties with this, anyone know how to fix it or what I might be doing wrong?

It varies as sometimes additional ad units won't display until the mediabot checks your page and other times there just may not be enough ads in the content network for your page.

Be patient, put the ads on the page and wait a few hours or a day.

I think the targeting of the ads has to be different in order to work. In a perfect world, one ad would be for widgets to go and one for widgets in a can. Try using the Google keyword tags around your ads to make sure they are focused on different topics.
