Vlookup error #Name?

[Navop]

Okay just learning this vlookup.

It worked before but now its gives me the following error ##### (#Name?)

this is the formula I used Vlookup(O$5$,Mois,2)

The value entered in O5 is a number between 1 to 12

I defined a table called Mois on a worksheet called Months

Mois = range a1 to b12 which is a 2 colum table.

a1 - a12 = 1 to 12 (number 1 to 12)
b1 - b12 = Jan, Feb, Mar (is the name of the months)

so 1 = Jan, 2 = Feb, 3 = Mar .......

If I edit name I get

Refers to = Months!$A$1:$B$12
Scope = Months

I have attached the workbook if needed

Thanks

Hi Navop and welcome to the board.

The named range is local scope to the Months sheet, thus;

=VLOOKUP(O5,Months!Mois,2,TRUE)

Hi Navop,

I'm curious... when you defined the name, did you explicitly make it scoped to the one worksheet? By default names are globally scoped... and your formula would work from any sheet.

[Navop]

made the scope to Months workbook

But I think I sovled the problem

Did a new table as above but put the scope to whole workbook

then I noticed it was not calculating, so look up the section calculation and it was set to manual..for some reason, placed it on auto and everything works fine...thanks for all the help

Hi

I posted earlier, but for some reason it didn't get througgh.

I wondered why you were jumping through such hoops with your dates?
You could get rid of the values in columns B and D and make the formulae as follows

cell C28
=DATE(P5,O5,N5)

Cell C29 ( and copied down )
=C28+1

Cell J24
=MAX(C28:C46)

This would make your task much simpler.

Thanks Roger for info

Like I said newbie at some formulas, was a friend that gave me other formula

Will change to new formula, easier to understand

Thanks again all for helping out...
