How to get name and in a sequence in Powershell -

when run below code error model number in heading not being displayed , 1 more thing unable 3 of them in sequence.

$arrcomputers = get-content -path "c:\desktop\computers.txt"     $e=$arrcomputers | foreach-object {get-wmiobject -class win32_bios -computername $_ } |select pscomputername, version,manufacturer,status,biosversion,serialnumber |convertto-html -fragment      $e2=$arrcomputers |foreach-object { get-wmiobject -class win32_logicaldisk -filter "deviceid = 'c:'" -computername $_ } | select freespace,size | convertto-html -fragment       $e3=$arrcomputers |foreach-object { get-wmiobject -class "win32_computersystem" -computername $_ } | select model| convertto-html -fragment       convertto-html -body "$e $e2 $e3" -title "list of computers" |  out-file c:\users\desktop\gf.html 

its lot easier make of wmi calls single object. easier handle formatting. think got wanting:

function getcompinfowork  { param (     [string]$computername,[string]$logfile )     $pc = get-wmiobject win32_computersystem -computername $computername      $bios = get-wmiobject win32_bios -computername $computername      $disk = get-wmiobject win32_logicaldisk -filter "deviceid= 'c:'" `     -computername $computername      $obj = new-object -typename psobject      $obj | add-member -membertype noteproperty `         -name pscompname -value ($bios.pscomputername)      $obj | add-member -membertype noteproperty `         -name version -value ($bios.version)          $obj | add-member -membertype noteproperty `          -name manufacturer -value ($bios.manufacturer)      $obj | add-member -membertype noteproperty `         -name status -value ($bois.status)      $obj | add-member -membertype noteproperty `         -name serialnumber -value ($bios.serialnumber)      $obj | add-member -membertype noteproperty `         -name disksize -value ($disk.size / 1gb -as [int])      $obj | add-member -membertype noteproperty `         -name sysdrivefree -value ($disk.freespace / 1gb -as [int])      $obj | add-member -membertype noteproperty `         -name computername -value ($pc.model)      write-output $obj  }  function get-compinfo  { param ([string[]]$computername,[string]$logfile )  begin {     $usedparamater = $false     if ($psboundparameters.containskey('computername')) {         $usedparamater = $true         } } process {     if ($usedparamater)      {         foreach ($computer in $computername)         {             getcompinfowork -computername $computer `             -logfile $logfile         }     }        else      {         getcompinfowork -computername $_ `         -logfile $logfile     }  } end {} }   get-content c:\users\kev\desktop\computers.txt| get-compinfo | convertto-html | out-file c:\users\kev\desktop\output.html
