Hi everybody,

I've added a new function to my Master.js file called CheckSelected. It is supposed to check if the item is selected in the listbox. However, I'm getting
CheckSelected is undefined error message when I try to click on the button.

The name spelling of the function is correct is cs and js files.

What do you think may be the problem and why my page could not find this newly added function?

I'm testing from IDE in FireFox.

Thanks in advance.
