Vista - Help with foreach-object and passing parameters

I'm new to powershell and I'm not quite getting the syntax to pass
parameters. I want to ping a list of servers that are listed in a text
file, and output the results to html...What I've figured out so far is:

import-csv servers.csv | foreach-object -process {get-wmiobject
win32_pingstatus -filter "address='www.yahoo.com'" | select-object
-property address,statuscode,responsetime} | convertto-html

That runs and loops the correct amount of times, and pings the
hard-coded www.yahoo.com. How do I replace the www.yahoo.com with the
values from my file?
Servers.csv contains:

Server
www.yahoo.com
www.google.com
www.lycos.com

I tried:

import-csv servers.txt | foreach-object -process {get-wmiobject
win32_pingstatus -filter "address='www.yahoo.com'"
| select-object -property address,statuscode,responsetime}

But that tried to ping @{Server=www.yahoo.com}, for example.

I did search pretty extensively and have suprisingly not found anyone
else posting about this same exact question.

Any help greatly appreciated!!!

Try this:

import-csv servers.csv |
foreach {gwmi Win32_PingStatus -filter "Address='$($_.Server)'"} |
select address,statuscode,responsetime

address statuscode responsetime
------- ---------- ------------
www.yahoo.com 0 37
www.google.com 0 36
www.lycos.com 0 120
