Method invocation failed because [System.Management.Automation.PSObject] doesn’t contain a method named ‘op_Addition’.

While constructing a PowerShell script for gathering information about Distribution Lists within a customers environment, I ran into the following error

Method invocation failed because [System.Management.Automation.PSObject] doesn’t contain a method named ‘op_Addition’.

This error was being generated by a missing array within my PowerShell code

# Call Distribution Lists

# Report on Distribution List
foreach ($dl in $dist)
{
 
  $count =@(Get-DistributionGroup $dl.samaccountname).count
  $report = New-Object -TypeName PSObject
  $report | Add-Member -MemberType NoteProperty -Name 'Group Name' -Value $dl.Name

  $reportoutput += $report
}

# Stop Transcript
Stop-Transcript

By adding the following lines to my above script I was able to successful export the required information into an Array and dump out to CSV.
