That was it!! I knew it was something small!

Not sure what I'm missing here. When I click the Total Cost button nothing appears in the text input. I've looked over the documents for any syntax errors but I am just not finding it!! This is an assignment. I need to the total to be inside the input text box. I'm just looking for another set of eyes to see if I missed a semicolon or something simple somewhere. HTML:

Another homework assignment so please just let me know what direction I should go in. Assignment details: Function: counter Parameter: An array of numbers Returns: The numbers of negative elements, zeros, and values greater than zero in the given array. Note: You must use a switch statement in the function. My JS file:

// Array of Numbers

var nums = new Array(-13,2,67,3,0,56,12,-41);
var len = nums.length;

for (i=0; i<len; i++) {
var count = nums[i];
}

var count = nums[i];

//Create counter function
function counter() {

switch (count) {
case "negatives":
    if (count < 0) {
        document.write(count.length);
    }
    break;

case "zeros":
    if (count == 0) {
        document.write(count.length);
    }
    break;

case "positives":
    if (count > 0) {
        document.write(count.length);
    }
    break;

default: {
    document.write("nothing!");
}

}};

I am not sure where to go with this one. I know it's the switch statement that throwing me off and I am not sure if my statement for counting each variable is necessarily correct either but I feel like I'm somewhere in the correct thinking here.

Oh geez! It's always the simple things that screw me up. I also noticed I was missing a semicolon after one of my statements too. Thanks for helping a beginner out!

I am currently a college student so please be kind to me being a novice! I am working on an assignment and I just can't figure out where I am going wrong. Assignment Details: Function: tst_name Parameter: A string. Returns: true if the given string has the form String1, String2 letter where both strings must be all lowercase letter except for the first letter and letter must be uppercase; false otherwise My JavaScript file:

function tst_name(name) {
// simple pattenr to check the format of the name
var ok = name.search(/^[A-Z][a-z]+, [A-Z][a-z]+, [A-Z]\.?$/);

if (ok == 0) {
    return true;
} else {
    return false;
}

} // end of function tst_name

// Test function with two sets of data
var tst = tst_name(Woods, Trista, M);
if (tst) {
document.write("Program error <br />");
} else {
document.write("Valid name. <br />");
}

var tst = tst_name(woods, trista, m);
if (tst) {
document.write("Invalid name <br />");
} else {
document.write("Program error <br />")
}

My HTML file:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd"
>
<html lang="en">
<head>
<title>Woods | Test Name | Exercise 4.12</title>
<script type="text/javascript" src="exercise4-12.js">
</script>
</head>
<body>
<script>
document.write("Woods, Trista, M: " + tst + "<br />");
document.write("woods, trista, m: " + tst + "<br />");
</script>
</body>
</html>

When I view this in a browser it just shows: Woods, Trista, M: undefined woods, trista, m: undefined So I'm just confused. I followed an example in our book and I just don't know what I need to do in order to get the variables to write the correct statements in my HTML document.
