If/else statements do not match up java [on hold]

I cannot paste my whole code, but my desired output is not coming up. I know there are a lot of brackets and if I delete all of them I get an error message.

        else{
            if (distance <= 500){
                if (weight >= 2){
                    rate = 1.10;
                    calculated_rate = 1.10;
                }
                else if (weight > 2 && weight <= 6){
                    rate = 2.20;
                    calculated_rate = 2.20;
                }
                else if (weight > 6 && weight <= 10){

                    rate = 3.70;
                    calculated_rate = 3.70;
                }
                else {
                    rate = 4.80;
                    calculated_rate = 4.80;
                }
            }
            else if (distance > 500 && distance <= 1000){
                if (weight >= 2){
                    rate = 1.10;
                    calculated_rate = 2.20;
                }
