UDF using Vlookup returning a VALUE error

[Pauline10]

Hello everyone,

I'm a debutant in VBA (and I'm French, so please pardon the English errors coming ahead !) and am trying to create a UDF including a vlookup.
The problem is that it returns a VALUE error.
I frequently have to vlookup values in a recurrent table, and so to save time I would like to create a UDF that already includes the reference to this table, the only variable would be the lookup value :

Function Vachercher(a As Variant)

x = Workbooks("C:\Users\julie DUPRE\Documents\21-02-17 - FACTURES 14-21.xlsx").Worksheets("Restitution").Range("B2:BT36000")

Vachercher = Application.WorksheetFunction.VLookup(a, x, 58, False)

End Function

I don't understand the VALUE error...I've checked several times that my references and my range are correct and it seems there are. I've also tried the same UDF but without an external reference to a workbook to see if that was the problem (so i tried the udf within the worksheet containing the table) but with no luck.

I would greatly appreciate some help !

Yes it is possible which is why I said

If the workbook was open you would use

I have tried a number of variations of this without success. What am I doing incorrectly?

Function vlook(LUCell As Variant)
Dim x As Range
x = Workbooks("Book12.xlsx").Worksheets("test").Range("B2:H6")
vlook = Application.VLookup(LUCell, Worksheets("test").x, 4, False)
End Function

It's just:

vlook = Application.VLookup(LUCell, x, 4, False)

and note that x is an array, not a range object.

RoryA: I did try that but it didn't work. Do I need to save the Book12 first?

Function vlook(LUCell As Variant)
Dim x As Range
x = Workbooks("Book12.xlsx").Worksheets("test").Range("B2:H6")
vlook = Application.VLookup(LUCell, x, 4, False)
End Function

I tried saving it as Book12.xlsm and changed the UDF accordingly. Still no luck.

As I mentioned, x is not a range. You should declare it as Variant.

DUH! Thanks, RoryA.

In that case I think you are out of luck. I know of no way for a UDF to access a closed workbook.
If the workbook was open you would use

Function Vachercher(a As Variant)

x = Workbooks("21-02-17 - FACTURES 14-21.xlsx").Worksheets("Restitution").Range("B2:BT36000")
Vachercher = Application.VLookup(a, x, 11, False)

End Function

Thank you very much, it finally works. It's a shame it can't be used with the workbook closed, but it still is very useful for me, so thank you !
