If statement not working - how to fix?

My if-statement does not go through the other ifs and just goes to the last elseif-statement without even checking the condition. I also have other if-statements similar to the one below but they are working just fine.

Cursor getSumWords76 = mDatabaseHelper.getSumWords(selectedID, "red");
    double red = -1;
    while(getSumWords76.moveToNext()) {
        red = getSumWords76.getInt(0);
    }
    red = (red/50)*100;

red_points.setText(String.format("%.0f", red) + "%");

if (red >= 20  && red < 40){
            red_bar.setImageResource(R.drawable.bar20);
        }
        else if(red >= 40 && red < 60){
            red_bar.setImageResource(R.drawable.bar40);
        }
        else if(red >= 60 && red < 80){
            red_bar.setImageResource(R.drawable.bar60);
        }
        else if(red >= 80 && red < 100){
            red_bar.setImageResource(R.drawable.bar80);
        }
        else if(red >= 100){
            red_bar.setImageResource(R.drawable.bar100);
        }
