Why nohup does not accept for loop?

I have this code inside a file called test.sh When I try to run

nohup ./teste.sh &

./ teste.sh: 9: ./teste.sh: Syntax error: Bad for loop variable

CODE

cuda="cuda.out";
cpu="cpu.out";
cudaTxt="cuda.out.txt";
cpuTxt="cpu.out.txt";
trash="/dev/null";
rm -f $cudaTxt;
rm -f $cpuTxt;

for ((i=10001;i<=1000001;i+=10000));
do
    echo "Cuda, $i iteração";
    head -n$i formulas.txt > formulas_pre-processadas_CUSTOMIZADA.txt;
    echo -en "$i\t" >> $cudaTxt;
    ./$cuda | cut -c19- >> $cudaTxt;
done;

for ((i=10001;i<=1000001;i+=10000));
do
    echo "CPU, $i iteração";
    head -n$i formulas.txt > formulas_pre-processadas_CUSTOMIZADA.txt;
    echo -en "$i\t" >> $cpuTxt;
    ./$cpu | cut -c19- >> $cpuTxt;
done;

echo "Acabou";
