onchange submits in FF, not in IE

[topher]

Here is the code; it works in Firefox, but not in IE:

<form method="post" action="ship.html">
<input type="radio" name="ship" value="8" OnChange="this.form.submit();">First Class Mail
<input type="radio" name="ship" value="7" OnChange="this.form.submit();">Priority Mail
</form>

What are my options with using a radio input to submit for IE?

(One situation where this does work in IE is if after clicking a radio button the user clicks anywhere else on the page - then the form does submit. Even a dummy button marked "submit" would work here.)

I thought this topic was about Final Fantasy. :(

Regardless, have you tried other mouse events, like;

<form method="post" action="http://www.google.com">
<input type="radio" name="ship" value="8" onmouseup="this.form.submit();">First Class Mail
<input type="radio" name="ship" value="7" onmouseup="this.form.submit();">Priority Mail
</form>

Or even onClick. onChange is for form elements that change, i.e., textarea, text, password, select . . .

onClick works - thank you!
