PowerCLI script to alert on snapshots in vSphere

Hello all,

I have been using the script from this website with great success.

http://vnucleus.com/2011/07/powercli-script-to-alert-on-snapshots-in-vsphere/

What I am trying to figure out, it how to modify the script so it will send out a report even when there are no snapshots on the VMs?

Can someone please let me know what I would need to do?

Thanks

Ray
