Careful using Adobe, you may get locked into a proprietary way of doing things.
Why not just use a standard HTML based form?
Here's a link with examples:http://www.w3schools.com/html/html_forms.asp
Note this example uses Microsoft ASP (Active Server Pages) to drive the form.
You can use this if your NetSol hosting package is Windows based.
If your hosting package is Unix, then you probably want to use PHP, a scripting language,
like ASP is.
Having said all that, when you click the Submit button, you decide what script you want to execute,
and in that script you have code that retrieves the form values.
If the form was not filled out completely, or supplied invalid values, your submit code should
return the user back to the form with an error message.
If all the values pass muster, then your submit script would then
do the emailing. For Windows, google for cdo sendmail code for ASP.
For PHP, I don't know.
If you want to save the values from the form, you submit script could
write those values to a text file on your server, or maybe insert that into a database
on your site. You'll need to research code on how to do that.
