hi all

i have a form with a few fields for user to enter, there's also a button which when clicked, a new textarea that has a html editor attached to it created, if the button is clicked again, the textarea will be removed.

the only problem is if i press the button 2 times, i.e. create the textarea then remove it again, when i try to submit my form, an error msg will popup informing me that something is null.

i know that e error is refering to my external javascript which creates the html editor, how do i solve this?

instead of pasting the code here, i pasted my code into notepad
http://www.geocities.com/dhaywirex/add.txt --my form's code
http://www.geocities.com/dhaywirex/editor.js --the html editor code
http://www.geocities.com/dhaywirex/editor.txt --if the one above cant work

I took a look but it's a lot of code, what exactly is null?

ok..heres the short stuff, when the button is clicked, it will call a function in editor.js, supply it with the name of the textarea created with panels.innerHTML = "<textarea name='panel' cols='50' rows='5' id='panel'></textarea>", and the function will create the html editor.
if i submit the form now, no problem
if i close the textarea, i.e. panels.innerHTML = "", the error, document.all[...].config is null or not an object will appear

the exact function called when button is clicked
function createForm() {
if (panelflag == false) {
  data = "<textarea name='panel' cols='50' rows='5' id='panel'></textarea>"
  document.form1.btn.value = "Remove Panels";
  panelflag = true;
}
else {
  data = "";
  document.form1.btn.value = "Add Panels";
  panelflag = false;
}

if (document.layers) {
  document.layers.panels.document.write(data);
  document.layers.panels.document.close();
}
else {
  if (document.all) {
    panels.innerHTML = data;
  }
}

if (panelflag == true) {editor_generate('panel');} 'from editor.js
}


the relevant function in editor.js where the error occured
function editor_generate(objname,userConfig) {
  // Default Settings
  var config = new editor_defaultConfig(objname);
  if (userConfig) {
    for (var thisName in userConfig) {
      if (userConfig[thisName]) { config[thisName] = userConfig[thisName]; }
    }
  }
  document.all[objname].config = config; 'i believe this is where error occured // store config settings
blah blah blah...lots more codes

hope this makes its easier to find out whats wrong
1 more thing, if i actually 'close' my textarea 3 times, the error will appear 3 times, close the textarea 2 times, and the error will pop up 2 times.....
