Powershell Script Monitor not working

Hello everyone! Really need some help trying to get this monitor off the ground.

We have a Windows Server 2008 Cluster and I'm trying to get the current owner of a resource. Unfortunately, I haven't seen anything in the Microsoft Windows Server 2008 Failover Cluster template that can do that or inform us if the resource has moved.

So we wrote a simple powershell script to tell us just that. The script executes successfully when run locally via the desktop. But for some reason, I can't seem to get to working using the PS script monitor. When I click get script output, it comes back as not defined

$fpstatus = cluster fpncluster res "alpha name" /status;

$fpcowner = $fpstatus[10];

$fpcowner = $fpcowner.substring(42,3);

if ($fpcowner -eq "alpha3"){

  write-host Message.Current Owner: ALPHA3;

  write-host Statistic: 3;

  exit 0;

  }

write-host Message.Current Owner: ALPHA4;

write-host Statistic: 4;

exit 2;

Can anyone assist?
