If an attorney submits an incorrect final order then what?

After a long drawn out process my ex and I finally came to an agreement. We put the agreement on record with the family court, and both dismissed any further pleadings against the other. Now his attorney submitted the order, but seemingly left out or altered everything my ex was to do. Now I have a court order that gives him everything he wanted, and all of my wishes were left out or wording altered to mean something else. My attorney is filing to have the judge look at the order and see if they will agree to revise it. My question is has anyone else delt with this and if so what was the outcome? Should I abide by our agreement that we entered into record with the court or the one his attorney submitted in the mean time? Oh by the way South Carolina law gives the attorney 30 days to submit the final order, and he waited 4 months!!!!I know what I need to do and am doing it, but just looking for someone who has delt with this, and wondering what their outcome was. Thanks
