It would help us if you read the red lettered words on the top of the page and state your State.
We also would need to know the following:
1. Was the judgment already awarded? If yes, date, time?
2. State Judgment was rendered
3. Level of court, i.e. small claims, district, magistrate, etc.
4. Is it default (you didn't show) or did you show? what happened?
My basic answer is this however: if it was already awarded, you usually have a certain amount of time in which to appeal the judgment. Check the court to see what the appeals process and time is. If you passed the appeals process already, than you are usually out of luck.
If you are within the time to file an appeal and there is an appeals process then you need to file your appeal in writing, you can usually ask the clerk if there is a form or if you can just write up something and file it with the clerk, then you need to actually follow the process for an appeals.
It would help us if you tell us more about your case, so we can assist you with a better answer.
