Hi Chrono is a field.
Chrono 7 = 25
Chrono 6 = 20
Chrono 7-Chrono 6 = 5
So as this student has a score greater than 1 i would want he/she counted. if she had a score of 0 or below then i would not want her counted.
So i need the above calculation to be in the expression
Hope that helps.
The expression you gave doesnt work as the score has not been worked out
