I am designing a form in classic ASP. I want users to preview the form once it is submited, and also give them the opportunity to modify the content. Please I need the ASP codes for these.

Uhm... you can't do that yourself?

You can look ASP FormMail example at http://www.brainjar.com/asp/formmail/.

This is sake of example. User enter name and email address..

For From Input page.

Name: <input name="Name" type="text" />
Email Address: <input name="Email" type="text" />

For Form Action page.

Display Name and email address: Write out Request.Form("Name") and Request.Form("Email")
Create submit buttons : "Submit" and "Modify"

If User hit submit, Send email,
Else Go back

Is this logical making sense to you? I am not ASP guru.. You can search it example on Google..
