Random Testimonial Block

can anyone help know how to modify cs-cart to make a block displaying a random testimonial rather than the most recent one? I tried the method described in an earlier post from 2008 but it doesn’t seem to work with the latest version.

[url]Smarty ::

More that likely throw this into the foreach statement located in view.tpl under /addons/discussion/

I couldn’t get that to work for me.
