How to create an offline link out of a ‘Next’ button?

Let’s say I have saved page A and B. I can only go to page B if I type in a userID in a box and click the ‘Next’ button under it. No password needed. [B]However, please note that in order to access page A, a user needs to logged in first.[/B]

This is the part I tried to modify in Page A’s source:

[code=html]<TD class=content_title width=”40%”>Input a User ID</TD>
<TD class=content_body><INPUT name=userID></TD></TR>
<TR>
<TD></TD>
<TD><FORM METHOD=”LINK” ACTION=”Page B.htm”><INPUT TYPE=”button” VALUE=”Next” onclick=”window.location=’Page A.htm'”></FORM></TD>[/code]

My question is which part in the source of page A I should modify in order to visit page B just by clicking the ‘Next’ button without even typing a userID? I want this to be done offline, because I am creating a demo version of the website.

Please don’t recommend any software or other ways to solve this. I need to know the code modification. Thank you very much!
