Getting Radio Button Values

[Maxmillian]

This may have been discussed before, if so, please direct me to the thread as I can't find it.   I am creating a plugin using the 'Selection' Field.  Any example will work for my question.  I will use the following:

Variable ID: active1
Option Type: Radio Buttons
Multiple Answers: No
Name 1:  Off    Value 1:  1
Name 2:  On    Value 2:  0

That is the basic setup, my question is how can I retrieve the value selected from the user input.  i am thinking the values are stored in and array blah.blah.active1 but am unsure how to explode or select specific array info from the provided proboards plugin variable.  Any help would be appreciated.

Okay, I was trying to make this to difficult.  It takes the value placed on the selected choice in the variable.  (for thos eintereated)
