multipage forms and session variables

[dee7]

i'm using session variables to store data input in forms spanning several pages.

but i noticed that once a value is assigned to a session variable, it maintains that value throughout the session - even if the user goes back and edits the form input, the previous variable value is maintained.

is there a way to alter values of session variables in this context or this a necessary restriction of such variables?

is it advisable to use hidden fields instead? or any smarter solutions out there?

help!!

i'm trying to use hidden fields but can't get it to work:

<tr>
<td> Email </td>
<td> <input type="text" size="40" name="App_Name"/></td>
</tr>

<tr>
    <td> Work/daytime phone </td>
<td> <input type="text" size="20" name="App_Phone"/><br /></td>
</tr>


<input type='hidden' name='var2' value='".$HTTP_POST_VARS['App_Name']."'>
<input type='hidden' name='var2' value='".$HTTP_POST_VARS['App_Phone']."'>


<tr>
    <td><br /><input type="submit" name="next" value="Next"></td>
</tr>

Help!!!

(PHP version installed is 4.0.3 hence using HTTP_POST_VARS[])

don't know if this is your prob, but both hidden fields are named var2, that shouldn't matter i wouldn't think, does anything echo into those fields
