Validating Form Data Using An Array

My input tags look like this per my book:
<input type="text" id="custEmail" name="custEmail" onblur="validate(this);">

Is having both name and id in there messing it up?

My brain's getting fried! lol I may have to submit what I have with questions to my instructor and hope he gets back to me in time to get it figured out and turned in on time on Sunday. Seems like plenty of time, but for some reason online instructors aren't "online" much!

You should be aware that the w3schools site is now very much out of date. As felgall says, it teaches 20th century Javascript.

<input type="text" id="custName" name="custName" onblur="validateName(this);">

<script type = "text/javascript">

function validateName (which) {
var val = which.value;
val = val.replace(/[^a-z\s\-]gi, "");  // strip all but letters (ignore case) and hyphens and spaces - Mary-Lou Smith
which.value = val;  // write it back to the field
if (val.length < 4) {
alert ("Your name must have at least 4 alpha characters");
which.focus();  // refocus on the incorrect field so compelling the user to make a valid entry
return false;
}
}
</script>
