Counting Exchange Transaction Logs

Trying to come up with a .ps1 that counts log files generated by Exchange (multiple DB's on multiple servers) on an as needed basis between backups.  Input file is a .csv of the format:

Server,DBName
server1,exdb11
server1,exdb12
server2,exdb21
server2,exdb22

Here is what I thought should work but gives me "token 'in'" errors on the ForEach or is not accepting the input to determine the network path to the file locations.

$PathNames = (Import-csv C:\ExServerDBs.csv)
  ForEach-Object ($P in $PathNames)
    {
      $ExDBLogPath = "\\" + $_.Server + "\d$\ExchangeLogs\" + $_.DBName
      (Get-ChildItem -Path $ExDBLogPath -filter "*.log").Count
    }

Any help insight or suggestions would be greatly appreciated.

Thanks!
