I read this thread and realized that it was exactly what I was looking for. The problem is I need it to be done with sentences not words. I have a problems with typing the same thought down twice in a large text column of thoughts and ideas. This piece of software that I found on thread thread89492 works really well for words, but not for sentences. I have not been able to figure out how to get it to work.
here goes the original code:

<title></title>
<script type="text/javascript">
function uniqueTownsLRN(frm){
var towns = frm.elements['inputText'].value;
var arrTowns = towns.split(/\s+/);
var arrNewTowns = [];
var seenTowns = {};
for(var i=0;i<arrTowns.length;i++) {
if (!seenTowns[arrTowns[i]]) {
seenTowns[arrTowns[i]]=true;
arrNewTowns.push(arrTowns[i]);
}
}
frm.elements['outputText'].value = arrNewTowns.join(" ");
}
function uniqueTownsDJS(frm){
var towns = frm.elements['inputText'].value;
var arrTowns = towns.split(/\s+/).sort(), ans = "", Had = "";
for(var i=0;i < arrTowns.length;i++)
if( Had != (Had=arrTowns[i]) )ans += Had + " ";
frm.elements['outputText'].value = ans;
}
function uniqueTownsRC(frm){
var towns = frm.elements['inputText'].value;
var st = '', seenTowns = {}, arrTowns = towns.split(/\s+/);
for(var c = arrTowns.length;c--;){
seenTowns[arrTowns[c]] = true;
}
for(var prop in seenTowns){
st += prop+' ';
}
frm.elements['outputText'].value = st;
}
</script>
</head>

<form name="testForm" action="" method="get"
onsubmit="return subTests()">
