How to display multiple banners from same invocation code

[steve bullman]

I need to display 12 banners from one invocation code. Looking through the resources I understood that I could just repeat the invocation code to make this happen, but that doesnt seem to have any effect. How can this be done please?

According to revive documentation all I need to do is add extra instances of the invocation code, but this doesn't seem to work. Am I missing a trick somewhere?
