This article aims to provide solution for one of the most common problems with vlookup. Vlookup does not work properly when source and destination data both occur in the same workbook or worksheet. This means, for vlookup to work properly, you should use two different workbooks (excel files) for source and destination. Let’s see why.
Following example illustrates #NA error due to the above mentioned issue (refer rows 7 and 9)
The problem here is that the selected range of source cells keep changing when you drag the formula down (while trying to copy it to other cells in the column). Check the following image which illustrates that the range will be different for each cell in column D.
To overcome this, you just need to make the range to a constant. It can be done by adding $ sign before and after the cell reference letter (here B and D in this example).
