Validation not working

In Data Assist I am using a form xxx_insert.php

I tried placing server validation but the opening box displays and does no more until I press the X top right side.

I then get two diplays of the attached image and that's that.

I tried applying Client Validation and that goes through the process to apply but the does nothing when the form is used.

Any ideas please what may be wrong?

Thanks

What extensions, including version numbers do you have installed?

I can see your Dreamweaver version is CS 3, What is your OS?

Here is an image listing extensions installed.

OS is windows XP sp3
Zip of file
Thanks

I see you have Form Toolkit, Form Builder, andHTML Editor installed.

with these extensions, they need to be installed in the correct order:

Form Toolkit
CSS Form Builder
HTMLEditor 3
Security Assist 2

I would try uninstalling them form the extension manager, then Delete the Dreamweaver Cache file from the users configuration folder:
common_installation_issues.php

and reinstall in the order listed above.

Thanks Jason
I reinstalled the extensions and will see how it works out.
