Hi, I have been staring at this for far to long and can't seem to see the problem. I keep getting the error message "undefined is null or not an object" when I run this piece of script. It is supposed to populate a 3rd select box based on the selection in the first select box from an array. Can someone look at my code an possibly tell me what I am not seeing? Thanks!
