want to ping then check for users loggedin

I'm trying to get this script to work, I want to ping a list of computers and if the computer pings, then run psloggedon; if the computer does not ping, then continue to the next computer, I get this error

ParserError: (:) [], ParentContainsErrorRecordException

foreach ($Computer in $Computers)

$status = @{ "ComputerName" = $Computer; "TimeStamp" = (Get-Date -f s) }
    if (Test-Connection $Computer -Count 1 -ea 0 -Quiet)
        {
      (if $status["Results"] = "Up")
        psloggedin
        }
        else
