Hi,

The formula should read

=IF(V2="","",......)

and it means if V2 = Null return Null

Null being an empty string

I am modifying a spreadsheet with a formula which looks something like this,
+IF(V2="","",......) The value in V2 represents the ID of the first column in
an array with information used to calculate distances between 2 points, the
corresponding points of which are represented as ID's in column V and W.

I cannot find anything in the help menu for the use of the empty string
value.
