Hello,

I need code allowing data already inputted in a form to remain if after "submit" is clicked, they need to go back and fill in remaining "required" fields they originallly left blank.

html code calling script in form is:
<form action="scripts/formmail.asp" method="POST">

Actual formmail.asp script is below.

Thanks in advance.

I'll set the input's value = to the Request.Form of that input. For instance...

<input type="text" name="Name" value="<%Request.Form("Name")">

And then I submit the form to my same page. If the page is first loaded Request.Form("Name") will not return anything so the value will be blank, if they submit the page and need to fix things you just call the sub to display the form and then it will be automatically populated by the last values they entered.

Or save the data to a session and use the same technique.



<input type="text" name="Name" value="<%Session("Name")%>">
