If you want to update your existing email form, simply copy the first FORM tag, and paste it over your current FORM tag. You will also need to copy each INPUT tag which says type="hidden".
I apologize, but we do not support any site design or coding.
What is a FORM tag? This is a form tag, starting with the less-than symbol and ending with the greater-than symbol, and it says "form, action equals something, method equals something".
<form action="http://www.mydomain.com/cgi-sys/formmail.pl" method="post">



<input type="hidden" name="required" value="field1,field2," />
and replace field1 and field2 with the names of your required fields.
You can have as many required fields as you like, just separate them with commas.
