Form valadation not working

Question

Hello All,
I am new to web design and Dreamweaver so I am hoping this is
somethign simple that I am missing. I have a simple form on a
webpage that I am trying to validate the fields before submitted. I
am using the "Validate Form" option in Dreamveaver. I have tried
validating the form onSubmit and the [Submit] button onClick.
Nothing is working and I cannot find any help online...I have
searched and searched...
Below is my code for the form followed by the valadation code
that Dreamweaver puts in the head tag:
<form action="gdform.asp" method="post" name="contact_us"
target="cont" id="contact_us">
<input name="name" type="text" id="name" size="30">
<input name="email" type="text" id="email" size="30">
<textarea name="message" cols="30" rows="5"
id="message"></textarea>
<input name="redirect" type="hidden"
value="form_feedback.html">
<input name="submit" type="image"
onClick="MM_validateForm('name','','R','email','','RisEmail','message','','R');return
document.MM_returnValue" value="submit" src="images/Submit.gif">
</form>
function MM_validateForm() { //v4.0
var
i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2];
val=MM_findObj(args
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must
contain an e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain
a number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is
required.\n'; }
} if (errors) alert('The following error(s)
occurred:\n'+errors);
document.MM_returnValue = (errors == '');
Is there something I have to add or change with this? I do
not know what to do to make this work. Any help with this would be
GREATLY appreciated!!! Thank you everyone for you time.

<form action="gdform.asp"
method="post" name="contact_us" target="cont"
id="contact_us"
onsubmit=
"MM_validateForm('name','','R','email','','RisEmail','message','','R');

<input name="submit"

value="submit now"

It's a bad idea for a form control have a value that is the
same as its
name. And your target doesn't look right.
