solution to a syntax problem

I'm trying to create a program where it goes by evaluating by sections a number of certain numbers but now that I try programs it appears to me that it has a syntax error

"parse error EOL usage might be invalid matlab syntax

TJ1=input('concentracion del tajo 1 '); %las concentaciones deben de estar en un rango de accion todas 
TJ2=input('concentracion del tajo 2 ');
TJ3=input('concentracion del tajo 3 ');
TJ4=input('concentracion del tajo 4 ');
TJ5=input('concentracion del tajo 5 ');
TJ6=input('concentracion del tajo 6 ');
TJ7=input('concentracion del tajo 7 ');
TJ8=input('concentracion del tajo 8 ');
TJ9=input('concentracion del tajo 9 ');
TJ10=input('concentracion del tajo 10 ');
TPL=input ('toneladas permitidas en planta ');
pe=input('error permitido '); %error permitido para el incremento 
C=input('concentracion a obtener ');
in=pe/100;
for i=1:in:TPL
    for j=1:in:TPL
        for 
            k=1:in:TPL;
            for
              l=1:in:TPL;
              for
                  n=1:in:TPL;
                  for
                      m=1:in:TPL;
                      for
                          o:in:TPL;
                          for
                              p=in:TPL;
                              for
                                  q=1:in:TPL;
                                  for
                                      v=1:TPL;
                                      CON=i*(TJ1/100)+j*(TJ2/100)+k*(TJ3/100)+l*(TJ4/100)+n*(TJ5/100)+m*(TJ6/100)+o*(TJ7/100)+p*(TJ8/100)+q*(TJ9/100)+v*(TJ10/100);
                                  end
                              end
                          end
                      end
                  end
              end
            end
        end

          end
          end

You have

        for 
            k=1:in:TPL;

This is not valid syntax. The loop expression must be on the same line as the "for" keyword.
