Error: not a data name in cobol program

I have a program that orders tables, but I do not know why in recorrer-tabla is highlighted in red and says "not a data name". On the other hand, if I place it a few lines above it takes it, but it does not do what I ask it to do is order the table.

This is my code:

program-id. Program1 as "ConsoleApplication2.Program1".

   data division

   working-storage section.
   01 tabla         pic 99 occurs 20
            indexed by indice.
   01 hora.
   05  filler           pic 9(6).
   05  hx           pic 99.

   01 variable-aux          pic 99.
   01 variable-paso     pic 99.

   procedure division.  

      set indice to 1
      perform rellenar-tabla until indice > 20
      set indice to 1
      perform display-tabla until indice > 20

      move 1 to variable-aux
      perform ordenar-numeros until variable-aux > 20
      stop ' '
      display '--------------------------------'
      set indice to 1
      perform display-tabla until indice > 20
      perform recorrer-tabla until indice > 20
      set indice to 1
      stop ' '

      goback.

   rellenar-tabla.
      display spaces upon crt
      display ' ' line 01 column 05
      accept hora from time
      move hx to tabla(indice)
      set indice up by 1
      display hx line 02 column 05
      stop ' '.

   display-tabla.
      display tabla(indice)
      set indice up by 1.

   ordenar-numeros.
      set indice to variable-aux
      perform recorrer-tabla until indice > 20
      add 1 to variable-aux
   recorrer-tabla.
       if tabla(variable-aux) > tabla(indice)
           move tabla(variable-aux) to variable-paso
           move tabla(indice) to variable-paso
           move variable-paso to tabla(indice)
         end-if
         set indice up by 1.


   end program Program1.
