Hi, now i do the sorted list for the combination i did. I want to read the data to the sorted list. But my foreach loop always had error. i fix it many times already but still can not solve it successfully. I will attach my coding. Hope someone can help me to solve the problem...
here is my coding. i will attach a full coding.
