Thanks Nik
let me explain

in the previous form i have created the inputfields as follows

the client chosses how many months will take to sell his inventory of
houses of a development (Development_ID
then he will forecast his sales through that period some months are better
than other

for($i=0;$i<$how_many_months;$i++)
    {
    <tr><td>MONTH<input type="text" name
"sales_forecast[months][]"></td></tr>
<tr><td>YEAR<input type="text" name= "sales_forecast[year][]"></td></tr>
<tr><td>SALES<input type="text" name= "sales_forecast[sales][]"></td></tr>
<tr><td>Product ID<input type="text" name= "[development_id][]"></td></tr>
    }
....(submit)..(form)...bla...
//As you have recomended i am using arrays to organize every thing is fine
until i get this type of dynamic tables

in the next page i want to run a one to check for the input content (not
included) another one to trim strip an htmlspecialchars and to insert
this works perfecly in one dimensional array where the array arrive gruoped
as sales_forescasrt[amount], sales_forecast[month] etc
so i just use the function insertar_tabla whixh means insert_table
I have been using print_r and have seen how the array are,_POST[x][y]
they are listed indexed one array after the other, first all the elements of
array since i use as name of the box the exact name as per the table i save
a lot of typing
but i cant figure out how to do it so i can input them in a similar manner
as with the function i use for one dimensional arrays
Nik
//this function checks for content and cleans
function insertar_tabla($array_to_insert,$table)
 {
 //echo("<br>Estoy registrando");
 global $mete;
  foreach($array_to_insert AS $key => $value)
   {
    $value=strip_tags($value, $tags);
    $value=htmlspecialchars($value);
    $value=trim($value);
    //echo("<br>".$key." ".$value);
    $keys[]=$key;
    $values[]=$value;

   }

//comenzamos en el segundo elemento el auto increment no pasa => segundo
elemento fecha_reg
  for($i=1;$i<$cuantos;$i++)
   {
   $joe=($keys[$i]."="."'$values[$i]'");
   $tom=$tom.",".$joe;
   }
  //esto es para que el primer campo no tenga coma
  $jim=($keys[0]."="."'$values[0]'");
  //concatenamos en una sola variable
  $insert_str=$jim.$tom;
  echo("<br>who = ".$insert_str);
  //$fecha_doc=date("Y-m-d");
  if(!($qitable=mysql_query("INSERT INTO $table SET $insert_str")))
   {
   echo("<br>Error en al insertar en  ".$table." ".mysql_error());
   }else{$msg="Su información";}

   $mete=mysql_insert_id();
   return($mete);
  }//FIN DE LA FUNCION
