I need limited scope representation

My husband and I are being sued by Barry White Family Trust because they do not want my husband to to pay tribute to Barry White with his Orchestra. While there are over 30 other tribute artist, they have come after my husband because we are close personal friends with Barry White's daugher who is suing the Barry White Family Trust. It is totally vendictive and retaliation. Because we cannot afford an attorney, I am representing my husband and I and have also filed a cross complaint. I will do the work, but I need help with filing papers with the court. I had to file an amendment which has some issues. I basically need help with filing papers with the courts.
The PDF titled 01 - 2021-12-17 Complaint is the error that the court has rejected. HELP PLEASE.
