Field not getting summarized...
I have few fields in my report out of which if i right click on one field it dosen't show me an option to insert Summary.
What could be the reason?
Do you have any Local, Global or Shared variable in that formula?
If so then I am afraid you will not be allowed to insert the summary for those variable.
In that case you will have to create the summary manually like below shown as example in the detail section.
and then on the Group where you want to display the summary just write this formula;
Make sure you reset the variable after displaying it into a sub section below where you displayed that.
Let me know if this helps.
