ActionScript 2.0 :: Adjusting Code Which Calculates Scores And Activates A Submit Button?

the basis of my problem is this. I have inherited some code which is a matrix of buttons which give a score of 1-7 depending on which button is pressed. The matrix consist of 7 rows and columns 7 buttons in each row and once all rows have a button pressed the final score is calculated and a submit button becomes activated (it is de-active until all rows have a score). This works fine, but I have added a function in which you can press another button which de-activates one row and activated another, so there are now 8 possible rows instead of 7, even though I want the total score to still calculate when there are scores of seven rows to tally up the total. The code I have now works with the first 7 rows, but when you add the 8th row it won't tally up the score, and activate the submit button.Anyway attached is the current code I am currently using:

Code:
function uClickBehScore(mc, rowParent) {
var codedName = mc._name
