Help: Need to calculate a radio button when selected or not selected

Question

I am hoping its possible to use a script to calculate a radio button when it is selected.  For example:
My form has 4 grouped radio buttons (Radio Button 1-4) of 5 buttons.
So its something like this:
     Level 1     Level 2     Level 3     Level 4     Level 5
1.   RB1          RB1            RB1           RB1         RB1
2.   RB2          RB2            RB2           RB2         RB2
3.   RB3          RB3            RB3           RB3         RB3
4.   RB4          RB4            RB4           RB4         RB4
Items areas total:               Total Points:               Average Score:
The buttons already have different values set for each button to calculate a score in the "Total Points" text field. (Level 1 scores 1, Level 2 scores 2, etc.)
I would like to have the "Items areas total" text field to calculate either a value of 1 if selected or a 0 if not selected.  So if 3 of the 4 rows are selected a return of "3" is calculated, if all 4 rows are selected then it returns "4", etc.
Seems it would be a simple script.
Thanks

Hi Franklin,
I understand that we can show the selected row in different color.
But still there is a requiremnet given saying that there should be an radio button or Select button or check box (Checked only one at a time of several rows) apart from showing the selected row in a different color.
Current display of the page:
We have three regions, 1> Main region, 2> Master region, 3> Detail region.
Main region has some text parameters, Master region has a adf:table and when ever you select a row on the master region the detail region values are getting refreshed based on the row selected.
Is there any simple way apart from adding a boolean transient attribute to VO and displaying it as one of the column in adf:table?
Thanks,
