ask 單身老貓 a question

I am suing someone in California to a small claim court. However, when I submitted the form, I made a mistake. The starting date of the incident should be 2003, but I mistakenly put 2004. I signed the form and sent it out. Today, when I received the confirm letter from the court, I realized the mistake.

If this mistake serious? What would the court do to this?

Thank you in advance!
