Okay, im having a little difficulty trying to code a #FollowFriday tweet generator for my website. My code works perfectly creating the tweet, but I want to make it so that when I hit the Submit button, it uses the text from the textarea to encode a URL and append it to the end of http://twitter.com/home?status=. For example if the text in the textbox says "#FollowFriday #FF @FATBOISLIMM" then it generates and opens this URL (http://twitter.com/home?status=%23Fo...%40FATBOISLIMM) in their browser window. Here is the code I have:

<script type = "text/javascript">

function text(t){
  a = document.getElementById('statusPreview');
  a.value += t;
function textCounter(field,cntfield,maxlimit) {
if (field.value.length > maxlimit)
field.value = field.value.substring(0, maxlimit);
cntfield.value = maxlimit - field.value.length;

function showtext() {
var output = "";
if (document.getElementById("chk1").checked) {
output = output + "#FollowFriday ";
if (document.getElementById("chk2").checked) {
output = output + "#FF ";
if (document.getElementById("chk3").checked) {
output = output + "@_SlapTV ";
if (document.getElementById("chk4").checked) {
output = output + "@FATBOISLIMM ";

document.getElementById("statusPreview").value = output;



<form name="status" action="http://twitter.com/statuses/update.xml" method="POST" enctype="application/x-www-form-urlencoded">

<textarea name="statusPreview" id="statusPreview" wrap="physical" cols="55" rows="3"
<input readonly type="text" name="remLen2" size="3" maxlength="3" value="140">
characters left
<input type="Submit" class="Submit" value="TGIFF">
<br /><br>

<input type = "checkbox" id = "chk1" onclick = "showtext()">#FollowFriday 
<input type = "checkbox" id = "chk2" onclick = "showtext()">#FF <br /><br />
<input type = "checkbox" id = "chk3" onclick = "showtext()">SlapTV 
<input type = "checkbox" id = "chk4" onclick = "showtext()">T
as you can see it generates the text just fine, but I dont know how to make it encode and open the URL. Please help!!
