Can someone tell me what I'm doing wrong?

I want to make the 2nd pulldown menu rely on the first one. When you select one of the left, for example "red line", then select another, like "blue line", some of the entries from the "red line" show up under the "blue line" in the 2nd pulldown.
When you select a pulldown, it should set all of the options to "null" before it assigns new options, yet it doesn't seem to be doing that to all of the entries. If you look, "Wonderland" should be the last entry for the "blue line", yet some of the "red line" entries are showing up @ the end.
This assignment is done in the function changeOptions(OptionsArr). The function is pretty striaghtforward, though, so I don't see how it should be performing incorrectly.
