Ok i have a page with a form on it. When the user clicks the submit button on a seperate page( doing it on seperate page due to limitaion sum users have 15" screens) it displays what errors they made and gives them a link back a page. with all the information they entered in still there.

that all pretty straight forward nothing fancy, however...

On the form that is being submitted i have a button that opens a window using java script and another that loads new window with a javascript calendar datepicker in it.

if either of those other windows is opened when i click the back button the users information that they entered for the entire form is wiped out!!!

How? Why?

how do i stop it?

The back button methods that i've tried :

Browser back button

Vbscript

<FORM method="POST" name="VBScript_Nav_Sample">
     <INPUT TYPE="button" NAME="Go Back!"
      VALUE="VBScript_Backup_Sample" LANGUAGE="VBScript"
      OnClick="call window.history.back(1)">
   </FORM>

and javascipt

 
<a href="JavaScript:history.back(5)">the past</a>

All work fine as long as the buttons are not pressed and the other windows not open up.

How can i stop my information getting erased?
thanks all for your help

Ok after hours of seraching for help. I've believe i've found the answer.

Its a bug in IE and old versions of fire fox. Updated FireFox and it works fine.

IE still not working so had to use client side validation.

Still going to use serverside validation for those people that dont have javascript. But if they make a mistake they will just have to enter the info again. :>

Remember Higginbt just because YOU updated your browser doesn't mean that everyone else is going to. If you want everybody to have the same functionality, you need to code for it.

The safest way to do this would be to pass the information back via form functions and reload them into the original fields and not rely on the browser's technology to do it for you. You will have to inculde an IF statement to make it work, but I would rather have the control as to giving the control to the browser..

Thanks for that. No i' aware that some people wont have the most uptodate browsers..

So i've fixed it clients side with Java script not allowing the form to be posted untill its details are entered correctly.

I know you now may say what if you dont have java. Well its still server side checked but the good thing about writing a car booking system to be used on the company intranet is i know every one here has java installed.
