PowerShell scripts works in ISE but fails as SQL agent job.

Hi everyone.

Could anyone offer my any advice on why this works when run in ISE but fails in SQL Agent job.

Script is :

$collection = $()
foreach ($server in get-content "C:\SQLSkills\PowerShell\All_SQL_Servers_Ping_names.txt")
{   
$status = @{ "ServerName" = $server; "TimeStamp" = (Get-Date -f s) }
if (Test-Connection $server -Count 1 -ea 0 -Quiet)
{        
$status["Results"] = "Up"
}    
else    
{        
$status["Results"] = "Down" 
}   
New-Object -TypeName PSObject -Property $status -OutVariable serverStatus
$collection += $serverStatus}$collection | Out-File C:\SQLSkills\PowerShell\pingresults.csv

Works in ISE as I say but fails when run in agent job. Agent account has privs to do task. Error message I get is :

Message
Unable to start execution of step 1 (reason: line(1): Syntax error).  The step failed.

Any help much appreciated.

Thanks
