I have a question- Suppose for particular column(say id) we have different marks in another column. But my question is if I am having same id with same marks while calculating average and percentage am not getting the right value because of that duplication. Can you tell me how to eliminate that please respond asap.Thanks!!
Id Marks
CD-IM22 12
CD-IM22 12
CD-IM22 12
Like this I have when I am doing the avg and percentage in the expression it is taking three- 12's instead of one-12 .How to eliminate that one. Please let me know. Anything we can do in scripting ??
