SharePoint 2013 Check folder exists in a document library using powershell

Following is a powershell function to check for a existence of folder in a document library.

Function CheckFolder($listParm)
{
    TRY
    {
        $ErrActionPref = "CONTINUE";
        $spQry = New-Object Microsoft.SharePoint.SPQuery
        $camlQry = "<Where><And><Contains><FieldRef Name='ContentType' /><Value Type='Computed'>Folder</Value></Contains></And><And><Eq><FieldRef Name='Title' /><Value Type='Text'>Name of Folder-To-Check</Value></Eq></And></Where>"

        $spQry.ViewAttributes = "Scope = 'Recursive'"
        $spQry.Query = $camlQry
        $spLstItms = $listParm.GetItems($spQry)
        if ($spLstItms.Items.Count -gt 0) 
       {
          foreach ($item in $spLstItms)
          {
             #items found
              return $true
          }
       }

    }
    CATCH
    {

     #Error handling
     return $false
    }
    return  $false
}



#I am calling this CheckFolder function as follows
if ((CheckFolder $list) -eq $true)
{
    #Matching folder found
}

When I run the checkFolder function, it is not finding the folder within the document library.

Any ideas on why it is not working.

Thanks

Nate
