To count the elements in this Source

Question

hi all,
I have a Source created by:
Source s = m1.join(m2).join(m3).join(d1).join(d2);
m1, m2, m3: MdmMeasure of the same Cube C1
d1, d2: MdmPrimaryDimension of the same Cube C1
I want to count the elements in this Source that have values so I used:
s.count()
I want to know the result of count() is the number of lines of m1 or m2 or m3?
Whith the same source like this, can I count the elements of m2?? If it's possible, show me how to do it please!
Always with the same source, is it possible to know which measure: m1 or m2 or m3 have the most elements not null?
I can count the elements of each measure then compare its together but in my exercice, I have 20 measures so I find a method that avoid the most request and comparison!
Thanks for your reply!

Guys - Thanks for the quick response
Bill - I think you are recommending the approach I had in the submitted code.
David - the whole point is that I want to use the pipeline, not the Path argument, and I had no luck with your suggestion, which I took as:
        Get-ChildItem $from -Recurse  |
            Where-Object {(New-TimeSpan -Start  $_.LastWriteTime -End $cutoff).TotalHours -le 0} |
            ForEach-Object {Copy-Item -Path $_ -Destination {Join-Path $to $_.FullName.Substring($from.length)}; $fileCount++}
However, all this did make me go read more documentation, and there is a -PassThru argument to Copy-Item which creates pipeline output after the copy.  Specifically:
        $fileCount=0
        Get-ChildItem $from -Recurse  |
            Where-Object {(New-TimeSpan -Start  $_.LastWriteTime -End $cutoff).TotalHours -le 0} |
            Copy-Item -Destination {Join-Path $to $_.FullName.Substring($from.length)} -PassThru |
            ForEach-Object {$fileCount++}
        Write-Host ("Copied {0} files/folders successfully at {1}" -f $fileCount, $(Get-Date))
Thanks again
