AICC score divide by 4

You can easily get the 60%. If you have the 120, just add an action to divide the 120 by 2. Now it gets a lot more complicated if you want the score to show the average of the tests taken. So if they have taken 3 tests, you want to divide by 3 not 4. Now you have to calculate what to divide by. Like this:New variable called num_testsnum_tests = 0add 1 if test 1 not equal to (and leave the value field blank)add 1 if test 2 not equal to (and leave the value field blank)add 1 if test 3 not equal to (and leave the value field blank)add 1 if test 4 not equal to (and leave the value field blank)Now divide AICC_Score by Var(num_tests)
