Excelchat Expert

Ok.

User

Yep

User

Im trying to load the info

Excelchat Expert
10/10/2018 - 04:48

Ok.

Excelchat Expert
10/10/2018 - 04:48

Can you just share the Vlookup here which you are using in the meantime you can build the info as required.

User
10/10/2018 - 04:50

Ok do you see this

Excelchat Expert
10/10/2018 - 04:50

Yes

User
10/10/2018 - 04:51

Is this formula correct?

Excelchat Expert
10/10/2018 - 04:51

The formula is correct but you need to make the range absolute.

User
10/10/2018 - 04:51

I have more data to add but its super slow because its too much

Excelchat Expert
10/10/2018 - 04:51

=vlookup(A2,Sheet2!A1:I54,1,false)

Excelchat Expert
10/10/2018 - 04:51

=vlookup(A3,Sheet2!A2:I55,1,false)

Excelchat Expert
10/10/2018 - 04:51

See the difference in both the formula

Excelchat Expert
10/10/2018 - 04:52

1st one is checking the data from A1 but the second is checking data from A2.

Excelchat Expert
10/10/2018 - 04:52

=vlookup(A2,Sheet2!$A$1:$I$54,1,false)

Excelchat Expert
10/10/2018 - 04:52

This should be your formula and then you copy it down.

Excelchat Expert
10/10/2018 - 04:53

So i have added $ to the range to make it absolute, so that when you copy the formula down, it will take the complete range for every search.

Excelchat Expert
10/10/2018 - 04:53

This is the reason you are getting less matches.

Excelchat Expert
10/10/2018 - 04:53

Does it make sense?

User
10/10/2018 - 04:54

Let me try it on my end

Excelchat Expert
10/10/2018 - 04:55

Sure.

User
10/10/2018 - 04:57

when you say absolute, should the table array be a specific column only?

Excelchat Expert
10/10/2018 - 04:58

Please copy and paste the exact formula you are using on your file.

Excelchat Expert
10/10/2018 - 04:58

Copy paste the first formula you have for the Vlookup here on chat.

User
10/10/2018 - 04:59

=VLOOKUP(A2,'Ramsey Cty Prim 2016'!Print_Area,1,FALSE)

Excelchat Expert
10/10/2018 - 04:59

so you have the range names as Print_Area

User
10/10/2018 - 05:00

ok, the second sheet is a print page

User
10/10/2018 - 05:00

how do I unformat that

User
10/10/2018 - 05:00

Im matching the vlookup onto the print page id

User
10/10/2018 - 05:01

is this an issue of print area?

Excelchat Expert
10/10/2018 - 05:01

Ramsey Cty Prim 2016 is the tab

User
10/10/2018 - 05:01

yep

Excelchat Expert
10/10/2018 - 05:01

Go to this tab

Excelchat Expert
10/10/2018 - 05:02

Then go to Formulas and Name Manager

Excelchat Expert
10/10/2018 - 05:03

You will see the "Print_Area" name listed there.

User
10/10/2018 - 05:03

the print area is the ramsey county tab

User
10/10/2018 - 05:03

so its included

Excelchat Expert
10/10/2018 - 05:03

I think if there is any error it is with the named range (if any)

Excelchat Expert
10/10/2018 - 05:04

Otherwise, I have to see the file to find the error.

User
10/10/2018 - 05:04

I see Printa Area in "Name Manager"

Excelchat Expert
10/10/2018 - 05:05

Ok. Select it and delete it. The again put the VLOOKUP formula using the absolute references as I explained above.

Excelchat Expert
10/10/2018 - 05:05

O

Excelchat Expert
10/10/2018 - 05:05

Or

Excelchat Expert
10/10/2018 - 05:05

If you select the name range, and click Edit - you will see the range it is for.

Excelchat Expert
10/10/2018 - 05:06

Please make sure it contains all the data.

Excelchat Expert
10/10/2018 - 05:07

Did it work?

User
10/10/2018 - 05:07

Excelchat Expert
10/10/2018 - 05:15

=COUNTIFS(L:L,"#N/A")

User
10/10/2018 - 05:15

Excelchat Expert

just replace L:L with the column in which you have N/A like B:B OR C:c

User
10/10/2018 - 05:16

There I get is there's too much unique id that I can't capture all of them
