Check the
www.ryanair.com website for flights from Montpellier to Frankfurt and from Frankfurt to Rome. It will take a lot of time flying and waiting in Frankfurt but it will get you to Rome and back for about 100 EUR if you book now.
Keep in mind that Ryanair flies to the Rome Ciampino airport and not to Rome Fiumicino like most airlines do.
