Lookup command - help please

[Peterw_2506]

Hi everybody,

I have a large worksheet where I need to tally up what the last number is on each row. The formula below works =LOOKUP(2,1/(I47:AO47>0),I47:AO47) but when I have a row that doesn't have figures in it yet the answwer I get is #N/A.

Can anybody tell me how to modify the formula so when there is no data in the applicable row the #N/A does not appear or a zero is left in the reporting cell.

regards, Peter

Hi Peter

=LOOKUP(9.99E+307,CHOOSE({1;2},0,LOOKUP(2,1/(I47:AO47>0),I47:AO47)))

Thank you this formula works nicely. I have found one bug however (you weren’t to know) in your formula =LOOKUP(9.99E+307,CHOOSE({1;2},0,LOOKUP(2,1/(I47:AO47>0),I47:AO47))) is it possible to use the concatenate command so the array I47:AO47 does not pick up everything in between I47 and AO47 but only pick up these cells (I47,M47,Q47,U47,Y47,AC47,AG47,AK47,AO47)

Regards, Peter

Try;

=LOOKUP(9.99E+307,CHOOSE({1;2},0,LOOKUP(2,1/((I47:AO47>0)*(MOD(COLUMN(I47:AO47),4)=1)),I47:AO47)))
