Ignore blank cells and truly blank cells in named range?

Question

Ok so my named range looks like this:
='Product Group Attributes'!$F$2:$F$1048576
However, I want to ignore the "" cells and the truly blank cells... However, I think all of them will have "" since I have this formula in all of the ones I'm putting in the range:
=IF(ISBLANK(C2),"",CONCATENATE(B2," - ",C2))
How do I go about getting these results into a named range so I can use it on validation since validation only seems to ignore truly blank cells and not the "" ones.

Answer 1

Actually, the "" cells means truly blank cells.
But the "Ignore blanks" in data validation does not mean it will remove blanks from the list. It basically means that a Blank will be allowed as a valid entry in the cell.
If you want to get rid of blank cells in the list, you have to create another list that does not include the blanks.
Use the VBA code below to copy data in column F to column G, meanwhile it will remove the blank cells.
Sub test()
Dim arr, i&
arr = Range("F2:F" & Range("F1048576").End(xlUp).Row)
For i = 1 To UBound(arr)
If arr(i, 1) <> "" Then s = s + 1: arr(s, 1) = arr(i, 1)
Next i
Columns(7).NumberFormatLocal = "@"
Range("G2").Resize(s, 1) = arr
End Sub
