BugFix dealing with edge fall off in Select module

The local variable edgeFallOff was being set instead of the field(Line 205). The getValue method was also using the control module instead of the second module(Line 122).

I submitted this as a pull request to the original repository as well, but yours seems like the most likely one to be updated.

By the way, I am not sure why, but the github editor replaced every line of code with what it was. All this means is that it shows 600 additions/deletions instead of 2. Feel free to make the changes yourself if you want to.
