One way to set it up for the DV control sought
Illustrated in this sample:
http://www.freefilehosting.net/download/3j2mb
Dynamic DV over several shts for unique selections.xls
In a sheet: DV,
Assume the DV items are listed in A2 down
Enter the source sheetnames in B1 across, eg: Sheet2, Sheet3
Assume the DVs are to be created in A2:A4 in each of the source sheets
Put in B2, copy across/filled down:
=COUNTIF(INDIRECT("'"&B$1&"'!A2:A4"),$A2)
Place in say, E2: =IF(SUM(B2:C2)>0,"",ROW())
Leave E1 blank
In F2:
=IF(ROWS($1:1)>COUNT(E:E),"",INDEX(A:A,SMALL(E:E,ROWS($1:1))))
Copy E2:F2 down. Col F will return the base list to be used for the dynamic
DV source
Create a dynamic defined range, say: MyR
to refer to:
=OFFSET(DV!$F$2,,,SUMPRODUCT(--(DV!$F$2:$F$6<>"")))
Now you can create the DVs using MyR as source in Sheet2's & Sheet3's A2:A4,
and you would have the exact control that you seek. Any DV items once
selected, will no longer appear/be availed for selection in the remaining
(unselected) DV cells in any of the source sheets. Test it out and see for
yourself. Extend to suit.
