Sorry, i should be more careful when posting examples ...
As JarC pointed out, it's the value="" you have to fill with your data and to add to the replacement, probably two times (username and password).
The name="" remains untouched and the size="10" needs to be changed only if your data string is larger than 10 chars.
In Topic ID 676, my Yahoo Form Filler, i needed to do that just once for the password.
So, hopefully correct this time
:
Match = "(*type="text" name="USERNAME")1(*type="password" name="PASSWORD")23"
Replace = "1 value="
My Username"2 value="
My Password"3"
"<script type="text/javascript">"
"setTimeout('document.loginForm.submit()',300);</script>$STOP()"
