I hope everything is okay !
I have a table that displays the recharge amount by telephone number
Tel number recharge amount
I would like to create a calculated filed sum of recharge amount whene recharge amount <2000 and sum of recharge amount >2000
You can create a flag like
If [Recharge Amt] > 2000 then
and then drag this flag to row/column and drag [Recharge Amt] to text as sum
Hope this could help
