Percentage Calculation

Hi, I need help creating a calculation field that would find the percentage of values obtained from radio button groups in acrobat 9.0.

I basically have ten radio button groups (ODIO1, ODIO2, ODIO3, ODIO4, ODIO5, ODIO6, ODIO7. ODIO8, ODIO9, ODI10).  They

each have six radio buttons/chocies that correspond to button values of 0,1,2,3,4, and 5.

I essentially need a calculation field that would display the percentage of the groups with the equation = (SUM(ODI01 - ODI10)/50) * 100%.

This would give me a value from 0-100%.

I have little experience in using Javascript, so any help in creating a Javascript to use this equation is greatly appreciated.

Thank You!
