[thelist] JavaScript: Find matching number in list

[Mike Carlson]

Howdy!

I have 3 drop down menus and each item in the menu is assigned a number.
After the user selects an option in each of the 3 drop downs, I need to
concatenate those together and then compare that string to a list of 3 digit
strings to see if there is a match in the list. If there isn't, bark at
them, if there is submit the form.

I am a newb in JS so I am looking at advice or examples that can help me
out.

Thanks,
--Mike
