Type mismatch error on my web page

Question

I have a web page which calling the Javascript function like below:
function initoptymenu(row, col) {
var a = document.applets.Tree;
var m = a.menu();
if (m == null) return;
m.removeAll();
if (row.substr(0,1) == 'Q') {
m.Add("View Quote");
m.Add("Mark active");
else {
m.Add("Remove Opportunity");
m.Add("View/Edit Opportunity");
But, when the event happen to call this function on my web page, I got an type mismatch error. and the java console shows the Error as :
netscape.javascript.JSException: Failure to evaluate initoptymenu('Q1831',0)
Could anyone know what I need to do the make it work?
Thanks so much.

It is kinda hard to tell without seeing the rest of the script....
But your script function is expecting a string and a number as arguments, but sure that the caller (which you didn't post) is supplying the correct type of arguments.
