how to count visible rows or columns?

[jmckeone]

Ran across another post on the board concerning code to count non-hidden rows. However it would not work as a normal Sub but was written as a function. I am new to VBA and haven't a clue how to run a function nor what the benefit is of using a FUNCTION over a Sub. Can anyone help with this code as well as explain this question?

Function COUNTVISIBLE(Rng)

' Counts visible cells
    Dim CellCount As Long
    Dim cell As Range
    Application.Volatile
    CellCount = 0
    Set Rng = Intersect(Rng.Parent.UsedRange, Rng)
    For Each cell In Rng
        If Not IsEmpty(cell) Then
            If Not cell.EntireRow.Hidden And _
                Not cell.EntireColumn.Hidden Then _
                CellCount = CellCount + 1
            End If
    Next cell
    COUNTVISIBLE = CellCount
End Function

A quick description of the difference between SUB and FUNCTION:

A Sub is the standard routine that you create for manipulating Excel. You can move around, create and delete sheets and workbooks, and do all the stuff you are used to doing. When you use the recorder, the result is a Sub.

A Function, on the other hand, will return a calculated result to one cell. Functions can't manipulate objects at all. You also store Functions in standard modules (like Subs), but you must create Functions entirely in code. To use this function, say you have a range from A1:A205. Some of these cells are hidden, and you want to count the visible cells.
In A206 you could enter =COUNTVISIBLE(A1:A205) to get the result.

Hope this helps

ok ... basically it is adding a custom formula type that can be accessed from the fx formula bar. Thank you.
