so what you want is to just put the number of times each name shows up in textarea 1, in textarea 2?

this is probably a bad way to do it, but it'd work:

you'd make textarea 1 a string...

var text1 = document.forms[0].elements[0]; //assuming its the first eleemnt in the form
var text2 = document.forms[0].elements[1]; //same deal

var text1_names = text1.value.split('\n');

for (var a=0;a<text1_names.length;a++){
  var names[a] = 0;
  for (var b=0;b<text1_names.length;b++){
    if (text1_names[a] == text1_names[b]){
      var name[b]=text1_name[b];
      names[b]++;
}}}
for (var c=0;c<name.length;c++)
  text2.value += names[c] + " " + name[c] + "\n";


i think that should work, though i haven't tested it

Dear devic,

Your function works fine, but I would need the frequencies side by side of names.

----------------------------------


Dear ren_b,

Yes, but deleting the lines in duplicate.

Please complete your function() to be most clear to me.
