I need to change a form so that instead of reloading the page after submitting it, it redirects the user to another page, this is the form:

<form class="questionform" name="questionform-0" id="questionform-0">

<textarea class="question-box" cols="12" rows="5"  id="question-box-' . $questionformid . '" name="title" type="text" maxlength="200" size="28"></textarea>

<input type="text" class="ubicacion" value="" name="question">

<input  type="button" name="ask" value="Publicar" onclick="askquestion('questionform-0'); window.location.reload(true);">

I want to remove the window.location.reload and change it for a redirect that sends users to the page their comment will appear. Which is:

www.chusmix.com/s?= (the content of the second field)

The problem is that the content of the second field is part of the url I want to redirect, it's not simply always the same URL. So I have no idea how to do it.

How do I do it? Anyway thanks for any info or whatever that points me on the right direction. Thanks
