onClick of textarea, autochange radio option

[Si]

I have a form with two radio options and a text area. The first option if highlighted by default. If the user clicks or tabs (onfocus) to the text area, I want the second radio option to automatically be highlighted.

eg. two radio's named "options", values "all" and "mine" and a textarea named "emails". "all" is already highlighted. When I click on "emails", I want "mine" to be highlighted automatically.

<input type="radio" name="options" value="all" checked>
<input type="radio" name="options" value="mine">
<textarea name="emails" cols="50" rows="10">
content</textarea>

Any help or ideas would be great.

Cheers
Si

Not sure if there's a better way of going about this, but this code seems to be working for me:

function checkSecondOption() {
	for(i = 0; i < document.forms[0].elements.length; i++) {
		if (document.forms[0].elements[i].value == "Option2")
			document.forms[0].elements[i].click();
	}
}
-----------------------------------------------------------

<FORM>
<INPUT TYPE="RADIO" NAME="Option" VALUE="Option1" CHECKED>Option 1<BR>
<INPUT TYPE="RADIO" NAME="Option" VALUE="Option2">Option 2<BR>
<BR>
<TEXTAREA NAME="Content" ROWS="5" COLS="50" onFocus="checkSecondOption()"></TEXTAREA>
</FORM>

Hope it helps!
