Need help with a PowerCLI script that won't fully execute to Remove Snapshots

I'm hoping someone can tell me why my script won't complete.  I'm trying to display and delete snapshots that are leftover by Commvault.  I have it written so I can search by Name or Description by removing the marking or un-marking your preference.  Everything works except for the section in "blue" below.  My variable, $snaps, shows the desired output but the code below it won't delete the snapshots.  It doesn't have any errors or give me a reason why it's not working.

* Parts of the script below came from other sources.

Hoping someone can assist me.

Thanks,

Charles
