all the text boxes.. and then when
down .. if a text box is empty goto
filledwrong.htm, if all full goto
the sendemail CGI

Hi Evan,

Lets say that there are two text boxes that need filling in, and a submit button to continue:

------------------------------------------------------
<SCRIPT LANGUAGE="JAVASCRIPT"><!--

function Submit() {

If (textbox1.value == "" OR textbox2.value == "") {
//Enter code to goto webpage or
//Have a messagebox popup like so:
Alert("Warning, All fealds must be filled in!")
}
else {
//Add code to goto page
}
}

--></SCRIPT>

Hope it helps.
