need assistance with a powershell script

need some assistance with this script, we need the script to complete each action before moving to the next. It is currently not working as expected.

$serviceName = "CryptSvc";
$serviceStatus = (get-service "$serviceName").Status;

if ($serviceStatus -eq "Running") {
    echo "service is running. Stopping CryptSvc now!";
    Stop-Service -Name $servicename;
}


if ($serviceStatus -eq "Stopped") {
    echo "CryptSvc is stopped. Starting CryptSvc now!";
    Start-Service -Name $servicename;   
}


if ($serviceStatus -eq "Running") {
    echo "service is running!";
    Send-MailMessage -To team@mydomain.com -Subject "Monthly Maintenance Reboot Successful!" -

Body "Monthly Maintenance Reboot completed successfully!

Service has been stopped and started successfully, and service is now running."  -SmtpServer 

10.1.2.1 -From test@mydomain.com;
}

elseif ($serviceStatus -eq "Stopped"){
    echo "service is Running again now!";
    Send-MailMessage -To team@mydomain.com -Subject "Monthly Maintenance 

Reboot Failed!" -Body "Monthly Maintenance Reboot FAILED!
