Likely Variable Scope Issue

i've done several tests , haven't been able figure out why variable not being recognized in invoke-command (it works @ other levels)...i've tested independently , works i'm not sure i'm missing. can set me straight.

if ($type -eq 's' -or $type -eq 's') {     $software = (read-host "enter software keyword: ")          foreach ($server in $servers) {         if (test-connection -computername $server -count 1 -quiet) {             $server             invoke-command -computername $server {                 $software                 get-wmiobject -class win32_product |                 where-object -filterscript {$_.name -like "*$software*"} |                 format-table -property name,version -autosize             } #end invoke         } #end if         else {write-host "could not connect: $server"}     } #end foreach     } #end elseif

the variable i'm having trouble $software.

i tested works using powershell v3... did copy code posted?

at point error? when run $scriptblock=... part?

$software='hp'
$scriptblock=[scriptblock]::create("get-wmiobject -class win32_product | where-object -filterscript {`$_.name -like '*$($software)*'} |format-table -property name,version -autosize") 
get-variable scriptblock | select -expandproperty value
#$scriptblock contains:

get-wmiobject -class win32_product | 
where-object -filterscript {$_.name -like '*hp*'} |
format-table -property name,version -autosize

are using version 2?

just confirm... ` character in `$_.name ascii code 96, not ' ascii code 39

i've tried above on computer powershell v2... creates same result as running on v3.
