meajie,
Have you ever thought about using some ActionScript and ColdFusion? Within your submit button use this code.
on (release) {
if (first_name eq "" || last_name eq "" || email eq ""

{
} else {
getURL("insert.cfm", "", "POST"

;
}
}
We're assuming your three fields will be first_name, last_name, and email. The CF page will call insert.cfm.
Then in your insert.cfm page use this code.
<cfinsert datasource="flashcfm.mdb" dbtype="odbc" tablename="flashcfm">
<cfoutput>
#first_name#,<br>
You submitted the following information into our database:<br>
First Name:#first_name#<br>
Last Name:#last_name#<br>
Email:#email#<br>
</cfoutput>
I used a MS Access db called flashcfm. This will take the three input text fields and pass them using CF to a Access database as well as give you a thank you for submitting page.
I hope this helps.
