Assistance with retrieving File and Version on a file with "custom file properties"

Question

Morning,
I am attempting to get the file version and date info from a file on multiple workstations on our network. I already know the file location, name and even which workstations the file is on. What I cannot get the script to do is query them and return
the file version/date info. I need this so that I can identify which workstations require an update.
Here is what we have written so far, but it errors out with "there is not a "in" for the "for each" statement. The "in" is there so I am missing something else that I just cannot see. I need to feed the workstation names
to the script and get the results out put to a csv file.
$application = New-Object -ComObject excel.application 
$application.Visible = $false 
$document = $application.workbooks.open("C:\Program Files\Common Files\SAP Shared\BW\sapbex.xla") 
$binding = "System.Reflection.BindingFlags" -as [type] 
$customProperties = $document.CustomDocumentProperties 
foreach ($Property in $customProperties) 
 $pn = [System.__ComObject].InvokeMember("name",$binding::GetProperty,$null,$property,$null) 
  trap [system.exception] 
     write-host -foreground blue "Value not found for $pn" 
    continue 
  "$pn`: " + 
   [System.__ComObject].InvokeMember("value",$binding::GetProperty,$null,$property,$null)  
$application.quit()
Thanks in advance for your time and assistance.
T.S.

I can't easily replicate that here since I don't have an appropriate XLA file handy.  Two ideas.
1. Run a few lines and see what's in the CustomDocumentProperties member:
$application = New-Object -ComObject excel.application
$document = $application.workbooks.open("C:\Program Files\Common Files\SAP Shared\BW\sapbex.xla")
$document.CustomDocumentProperties
2. Change the foreach to a ForEach-Object by replacing "foreach ($Property in $customProperties) {" with "$document.CustomDocumentProperties | ForEach-Object {  $Property = $_ "
