nested |rotate|

Hi,

How could I use nested |rotate| ?

for example:

on the same height I want to have two ads,

ad1 ad2

but ad1 would be rotating between ad1a, ad1b, ad1c

then ad2 would be rotating between ad2a, ad2b, ad2c

I’m using php code

for example:

<?php if (function_exists (‘adinserter’)) echo adinserter (1); ?>
