Set a flag

I have a script that is performing a tak in a loop.  I am generating an email and would like to somehow set a flag across the whole script that can identify if one instance of the task has failed.

Would this be as simple as setting a flag or is there a proper way in Powershell\.net to do this?  Code as follows

#Check if there are any error counts, if there are something has gone wrong restoring the DB
if ($errs -ne 0) {
    "Something failed when restoring the database...Check the following error(s)..." | out-file -append $GenericLogFile
    $i = 0
    For(;$i -le $errs; ) {
        #Scrape the errors out and post to the log file
        $error[$i] | format-list -force | out-file -append $GenericLogFile
 $i++

#------This is the flag------#

$broken = $true

    }
} else {
   " Restored Succesfully" | out-file -append $GenericLogFile

}

Then I'd check wheather $broken was true\false and act accordingly...
