@Abhinavpandey

removing an item while iterating over the list on the same time is not possible
for reseting a list you can do following:

  • new List(of Yourdatatype) within an assign
  • clear collection activity

issue resolved.

used clear collection activity outside the for each loop,
its working fine. the length was zero
the assign sum to zero
for next iteraction the sum is not appended
