Javascript error

I have this Javascript code:
function chk_vals() {
		alert("ac = " + ac);
		if (ac == "n") {
			document.st.action = "main.php";
			return true;
		if (ac == "rm") {	
			alert("got to ac = rm");
			ne = document.getElementById("st").elements.length;
			alert ("ne = " . ne);
			nchkd = 0;
			for (i = 0; i < ne; i++){
				if (document.st.elements[i].type == "checkbox") {
					if (document.st.elements[i].checked) {
			alert("nchkd = " + nchkd);			
			if (nchkd >= 1) {
				document.st.action = "remove_sels_fr_proj.php?pid=" + pid;
				return true;
			} else {
				alert("Please check at least one selection.")
				return false;

Open in new window

<form method="post" name="st" action="load_proj.php" onSubmit = "return chk_vals();">

When I run it, it displays the first two alerts (up to & including alert("got to ac = rm");

No more alerts, & it goes to the default action, NOT the new action specified here.

What's wrong?

If it is not displaying "alert("nchkd = " + nchkd)" then the 'break' on line 16 is probably taking it out of the function.

zc2, I changed it as you suggested, it helped, but the alert on line 10 says undefined. I realized I was using the php concatenate, changed it to + so it now reads alert("ne = " + ne), and it works.
