I want to count the number of unique text values that appear in the same column but over four separate worksheets.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
ffice
ffice" /><o
></o
>
<o
> </o
>
So far I have found the following formula which works for a single worksheet but obviously cannot sum this across multiple worksheets as each formula will not take account of the unique values counted in the previous formula.<o
></o
>
<o
> </o
>
=SUM(IF(FREQUENCY(MATCH('Sheet1'!DH:DH,'Sheet1'!DH:DH,0),MATCH('Sheet1'!DH:DH,'Sheet1'!DH:DH,0))>0,1))
(With DH being the column I am counting in each Worksheet)
<o

It seems like a simple thing I am trying to do but the Excel requirement seems more involved.<o

Does anyone know the answer to this?
