Excel messes with my formula when copied, how can I stop I stop it changing one part but not the other?
Solution 1:
The names are Absolute and Relative cell references. The $ turns either a row or column absolute so they do not change when filled or copied to a new location. You were filling down rows so you only needed to 'lock' the row numbers as absolute. If you put the cursor into the cell address and hit F4, you will see the first of the combinations. Keep tapping F4 to see other combinations.
=VLOOKUP(A2,'PhoneType - Email'!B$1:V$29190,3,FALSE)
