Please help! I have a form with checkboxes. When one or more checkboxes are clicked, I want the program to dynamically create a div, assign that div an editable text area, then when user clicks submit, I need it to gather the input from EACH textbox and output that to another textbox. I can't figure out what I'm doing wrong. It always tells me "Object Expected" on clicking the checkboxes. If I have it completely wrong, Please bear with me - I'm still learning! :)

First in the code posted above there are syntax errors at line 29. Since you are assiging a string to a variable and that string has single quotes you have to escape them correctly as follows,

newdiv.innerHTML = '<br>Please copy and paste additional information here<input type=\'textarea\' id=\'mytext\''+i+'\')>';

Now on line 26 you are trying to create a new element as

var newdiv = document.forms['example'].createElement('div');

But you cannot create a new element on form element. You will have to create a new element on document and than append it as a child to form element as follows,

var newdiv = document.createElement('div');
document.forms['example'].appendChild(newdiv);

Hope this helps
