When a case is Reversed and Remanded what does that mean?

When a case is decided by a trial court, the losing party may appeal the case to an appellate court. If the appellate court finds that the trial court made a mistake, as a matter of law, then the judgment may be reversed meaning that the court is invalidating the trial court's decision. It is then remanded, meaning sent back to the trial court, so that a judgment in the losing party's favor will be recorded.
