Hi. As you can see, I have these user data and I want to sum up those IBTs after some certain blogs with IBT>60.
e.g: for user 11, the sum is 0 for there is only one blog after the IBT>60 blog.
and for user 22, the sum is 1.
for user 33 and so on. (Those blogs with IBT>60 are not always the first blog.)

.
I have tried your way of marking those blogs with IBT>60 by rule engine, but I donâ€™t want to sum these IBTs. Or let me explain it in another way: I want to sum up the IBTs of these users once they post the IBT>60 blog. I uploaded the aggregated data and marked some IBTs that I want to sum up.
Can rule engine or other codes can help me with that?

Hi @Alexiaiaa , @mlauber71 was asking for a sample file, not a screenshot. In addition to that, some rules need to be made clear e.g. what if there is only one row of data for a particular ID - and how will the calculation be applied to this special case based on its value?

Hi @badger101 Q.xlsx (606.8 KB)
I uploaded an xlsx file of the data so that you can try it @mlauber71. I marked those blogs with IBT>60 and the last blog of each user, all I need is to keep the rows between â€śnot sumâ€ť and â€ślast blogâ€ť, and then sum up their IBTs.
About the rules, this table only contains users who post at least two times and each of them only has one blog with IBT>60.
BR!
