You can't. This is a security feature of HTML and has nothing to do with
ASP.Net. html input values are read only. If they weren't, anyone could
put a hidden html input field and set the value like "c:\passwords.txt" and
when the user clicked any button they'd have their passworsd.txt file
uploaded without ever knowing it.

CMIIW, but that's only true if the input's type is file, and the form's
ENCTYPE attribute is "multipart/form-data".

You need to response.write the variable's value into the html:

<input type="hidden" value="<%=nTotal%>">

doh...for some reason I read that it was an HtmlFileInput control :)

anyways, why use the old ASP method of Response.WRite? Declare it as a
webcontrol and set the value programatically.

I'm still in the learning phase myself. My mind is still firmly entrenched
in the classic ASP way of doing things.
