Hi ,
I'll try to explain :
1. You have two workbooks , one named Lookup Data Example.xlsx , and the other named Lookup Data Groups.xlsx
2. You are using the VLOOKUP formula in the first workbook , the one named Lookup Data Example.xlsx
3. The exact formula would be :
=VLOOKUP(F2,'[Lookup Data Groups.xlsx]Lookup_Data_FileServer'!$A$2:$F$7,6,FALSE)
Copy this to your file and see if you still get the error. If you do , then it is clear that the data in cell F2 of your workbook named Lookup Data Example.xlsx does not exist in column A of your workbook named Lookup Data Groups.xlsx
If you do not want to find the lookup value in column A , but in column F , then change the range from $A$2:$F$7 to $F$2:$F$7 , and change the third parameter from 6 to 1.
I am assuming that you have copied and pasted the names of your workbooks and worksheet exactly.
