I am trying to set up a formula that will return the data in the last cell in
a row. The problem I am having is that the row grows daily. Therefore, if
the Cell I want the data to populate in is I3, then my row goes from J3 to
infinity or at least Z3 as I add to it. Therefore, I3 should return whatever
cell is the last cell in the row with data in it. I have tried an IF
statement but it is very long and it only allows me to input upto 8
statements or upto only R3. Any suggestions?

Here is the statement that I am using:
=IF(R3=0,(IF(Q3=0,(IF(P3=0,(IF(O3=0,(IF(N3=0,(IF(M 3=0,(IF(L3=0,(IF(K3=0,J3,K3)),L3)),M3)),N3)),O3)), P3)),Q3)),R3)
