Textarea onchange function

Hi,

I have some text above a a textarea that displayed (saved) after a form is submitted, I would like the text to change to not saved after the text are has changed

Here is the code I tried, doesn't seem to be working.

Edit:
Kinda got it working using onfocus="internalsave.innerHTML='Not Saved'" seems to work, but when I tried
onfocus="document.getElementById('internalsave').innerHTML='Not Saved'" it doens't seem to work. Using IE6.

Any ideas?

Thanks


Internal Notes <div style="color:#CC6600" id="internalsave">(Saved)</div>
<textarea name="Notes_Notes" rows=12 wrap=hard cols=58 onChange="document.getElementById("internalsave").innerHTML="Not Saved";">blah</textarea>
