I've successfully implemented CMSMS on my new site...thanks to a couple of postings

I'm hoping somebody can help me with one last piece...
I'd like to have the submenu block only appear IF there are pages under the parent. I can always create a template for each section but this obviously would be very clunky and not dynamic.
As an example, please view one of my site sections - http://executivedesigns.com/orange-prot ... =project-2
This works great, however, if there weren't any projects in this area, I would want the submenu in the lower right - along with it's header - to NOT appear.
I've included the code for this block below if it helps.
Any ideas would be most appreciated...thank you!
