Hello Team,
I have a sheet with several tabs, Tab1 extracts data from 3 other tabs using vlookup, where the data in these 3 tabs is changed each month.
how can I make vlookup functions in Tab1 work automatically once I put the new monthly data in the other 3 tabs.
For now, I have to write vlookup formulas in tab1 every month as it doesn't work otherwise.
Another issue please, Mostly after applying Vloopkup I get some cells with #NA, when I write the same formula again in these cells it gives me the output as expected in some cells but also some few cells give me #NA & i have to write the formula again& again till all are completed.

Excelchat Expert

I'm afraid our policy is maximum 1 hour per session. If you think you can't continue this time, the chat will end automatically in 1 hour unless you choose to end it before. If you come back after 2 hours, you have to open a new chat

Excelchat Expert
26/09/2018 - 09:12

Which cells these formula's are referencing to.

Excelchat Expert
26/09/2018 - 09:13

Umm, we can try without the file though.

User
26/09/2018 - 09:15

well.. ok, then that would be good ..

Excelchat Expert
26/09/2018 - 09:15

In that case it might take a lots of Q&A between two of us to figure out the problem.

User
26/09/2018 - 09:15

at least we may be able to get something

Excelchat Expert
26/09/2018 - 09:15

Yeah, sure.

User
26/09/2018 - 09:16

User
26/09/2018 - 09:16

Excelchat Expert
26/09/2018 - 09:16

What does the named range Name contain?

User

or

User
26/09/2018 - 09:17

=VLOOKUP(A2,JulCap!A2:D135,4,0)

User
26/09/2018 - 09:18

the name range has normal text .. only 1 word & I make sure that no spaces are there

Excelchat Expert
26/09/2018 - 09:18

The look up ranges are always the same even after change of data?

User
26/09/2018 - 09:18

mm.. not sure I understand the question..

Excelchat Expert
26/09/2018 - 09:19

JulCap!A2:D135 this part of the formula is lookup range.

User
26/09/2018 - 09:19

yeah

Excelchat Expert
26/09/2018 - 09:19

This range changes when you paste new data for new month?

26/09/2018 - 09:20

yes.. but all the ordering of columns are the same only some values in some cells are changed each month ..

User
26/09/2018 - 09:21

but I copy the data from another sheet each month & then paste it in the JulCap tab

Excelchat Expert
26/09/2018 - 09:22

Do you delete the old columns before pasting new data?

User
26/09/2018 - 09:22

sometimes I do so & sometimes I just paste it above.. & it's the same results still

User
26/09/2018 - 09:22

Excelchat Expert

Unfortunately with these information it looks like everything is alright and you shouldn't get the N/A error.

Excelchat Expert
26/09/2018 - 09:29

And I am not able to figure our why you are getting those errors just from those information.

Excelchat Expert
26/09/2018 - 09:29

Excelchat Expert
26/09/2018 - 09:34

Not sure if it would help, but you can try this. On the Excel ribbon, go to the Formulas tab > Calculation group, click the Calculation Options button, and select Automatic

Excelchat Expert
26/09/2018 - 09:35
