Set Textarea value not working

<SCRIPT language="JavaScript">
function chgText (what) {
 var myString="This is line one.\nThis is line two.\rThis is line three.";

<FORM onsubmit="return submit_form()" action="caseNewPost.asp" method="POST" id=frmNew name=frmNew>

  <SELECT id=cbxCategory name=cbxCategory style="WIDTH: 200px" onChange="chgText(this)">
    <OPTION  value="0" selected>(None)</OPTION></SELECT>

<TD colspan=4><TEXTAREA id=txtDescription style="SCROLLBAR-SHADOW-COLOR: white; SCROLLBAR-TRACK-COLOR: white; WIDTH: 100%; HEIGHT: 140px" name="txtDescription"></TEXTAREA></TD>

Those are the relevant lines of code I am dealing with.  Can someone tell me why the textArea is not getting the value that I am sending to it?  I tried to put an alert in the function to make sure I was getting to the function and I was.  I changed the txtDescription in the function to a bogus entry and got an error.  But with this code I get no error and I get no result also.  Someone please help, I am ready to pull my hair out on this one.

Should have a lower case 'v' in value like this:
