defining specific frame?

hey guys. I’ve found some code online which appears to be exactly what I want, basically replicating the CTRL + F function of the browser itself. I’ve been successful at getting it to work, only I can’t quite understand how to define which frame I would like it to work with, instead of it “self”. I’ve posted the code below. Thanks for any help!

<!– EXAMPLE FORM OF FIND-IN-PAGE SEARCH USING SUBMIT (ALLOWING ‘ENTER/RETURN’ KEY PRESS EVENT) –>
<form name=”form1″ onSubmit=”search(document.form1, frametosearch); return false”><input type=”text” name=”findthis” size=”15″ title=”Press ‘ALT s’ after clicking submit to repeatedly search page”> <input type=”submit” value=”Find in Page” ACCESSKEY=”s”></form>

Hopefully someone will have some luck with this one!
