excel vba problem - function calls from cells
 

I have a vba function that I'm calling from a cell. It is supposed to
unhide a sheet copy some information to that sheet, do an advanced
filter, and fill some cells with a formula to count the number of
occurances of each value. I have some autofilters on my sheet and a
cell that changes when a filter is done. When I load the data into my
sheet the function works. However when a filter is performed it
doesn't run any of the commands in the function. I can trace it
walking through the commands, but it does not perform any of them.

I have another function that performs with the same result. I have 12
other functions that work just fine and are called in the exact same
manner and work just fine all the time.

Anyone know what could be going on?

internerdj,

My guess is that the ones that work aren't functions, but are subs, and the
one that doesn't work is a function. Functions can only return a value to
the cell that contains the function call - all other code acting on other
cells, filtering, etc. is ignored, though you can step through the code
fine.

Nope thats not it. All of my calls from the spreadsheet are directly t
functions. Since the calls ignore the lines about other cells, wha
can I do to force these functions to actually execute when a filter i
performed?

What is going on is that I need a chart that will give me a bar grap
showing the count of each unique equipment type in a column, and I nee
it to update automatically to chart only those values that are shown b
the filters

One way to force a User-Defined-Function to calc when a filter is updated is
to include a SUBTOTAL function call, but one that doesn't actually do
anything, along the lines of:

For numeric values:
=UserDefinedFunction(A1:A100) +IF(SUBTOTAL(9,A1:A100)0,0,0)

For string values:
=UserDefinedFunction(A1:A100) & IF(SUBTOTAL(9,A1:A100)0,"","")

I'll do my charting function since it is smaller:

Thats essentially what I'm doing...
=IF(H40,ChartObject(),"")
Where
H4=SUBTOTAL(3,B8:B5008)

THIS ONE DOESN'T DO ANYTHING WHEN A FILTER CHANGES

-Function ChartObject()

Dim i As Integer, stringer As String, stringer2 As String

Worksheets("Charts").Activate
Charts.Add
ActiveChart.ChartType = xlColumnClustered
Worksheets("Calculations").Visible = -1
ActiveChart.SetSourceData Source:=Sheets("Charts").Range("H10")
i = 1


While i < 255
stringer = Str(1 + i)
If (i + 1 < 10) Then
stringer = Right(stringer, 1)
Else
If (i + 1 < 100) Then
stringer = Right(stringer, 2)
Else
If (i + 1 < 1000) Then
stringer = Right(stringer, 3)
End If
End If
End If

On Error GoTo done

If Worksheets("Calculations").Range("H" & stringer).Value = "
Then GoTo done
If Worksheets("Calculations").Range("H" & stringer).Value = "
Then GoTo done

stringer2 = "=Calculations!R" & stringer & "C6"
stringer = "=Calculations!R" & stringer & "C8"

ActiveChart.SeriesCollection.NewSeries

ActiveChart.SeriesCollection(i).Values = stringer
ActiveChart.SeriesCollection(i).Name = stringer2
i = i + 1
Wend
done:
ActiveChart.SeriesCollection(1).XValues = "=Charts!R7C3"
ActiveChart.Location Whe=xlLocationAsObject, Name:="Charts"

Internerdj,

Acutally, I would be more interested in the functions that you think
work.... The rules of VBA functions are thus (for functions called from
cells):

Function MyFunc(myStr As String) As String
MyFunc = "This is a legal return."
Range("A1").Value = "This line causes an error, causing #VALUE! to be
returned."
End Function

Function MyFunc2(myStr As String) As String
On Error Resume Next
MyFunc = "This is a legal return."
Range("A1").Value = "This line is ignored because of the On Error Resume
Next."
End Function

E1SUMG does work, but it only retrieves data from cells in the shee
until it returns.

Is there a way to do what I need when an autofilter is changed
