So I have a dataset as follows
NaN 51.1512 4.0000 6.0000
NaN 80.7646 3.0000 6.0000
NaN 89.3755 2.0000 6.0000
NaN 96.3119 1.0000 6.0000
NaN 51.1512 8.0000 5.0000
NaN 80.7646 7.0000 5.0000
5.1104 89.3755 6.0000 5.0000
NaN 96.3119 5.0000 5.0000
9.0177 51.1512 12.0000 4.0000
NaN 80.7646 11.0000 4.0000
5.3294 89.3755 10.0000 4.0000
now, I want the element in row 3, for a value of say 5 from row 4 and a value of 89.3755 of row 2, which is 6.0000.
Can you tell me how to do that? Thanks!

I am not sure, but I think you are confusing rows and columns, which makes your question not clear
