Hello,
there are several approaches for the first part of your question, for example
=sum(c10:offset(C10,47,0))
=sum(offset(C10,0,0,47+1,1))
For the second part of your question, you can use an IF function to check if a certain value is reached and then return something. An example of your data structure would help. You may want to put that into a new question.
