Solved: Regression Analysis macro

I am working on automating a regression analysis for our field staff but I am running into a problem referencing the cell range for the regression. Essentially, I have a pre-made form that the sales staff fills out and then runs one of two macros depending upon what type of regression analysis is desired. These macros populate the data form that is the base of the regression analysis. This form could have anywhere from 1 to 88 entries. I am trying to find the last cell used (yLast) in the named range and by using an offset set the xLast cell. I can find the last y value cell and get the offset to the xLast cell but when I try to use these as a reference in the regression code, I get an "application or object defined error.

Here is the code:

Code:

---


Private Sub CommandButton1_Click()

'code to run regression analysis
Dim yFirst As Range
Dim xFirst As Range
Dim yEnd As Range
Dim xEnd As Range
Dim yRng As Range
Dim xRng As Range
With Range("RegRng")
    Set yEnd = .Cells(.Cells.Count).End(xlUp)
End With
Set xEnd = yEnd.Offset(0, -1)

Set yFirst = Sheets("Data Summary").Cells(10, 5)
Set xFirst = Sheets("Data Summary").Cells(10, 4)
   
 'code to run regression - This is where the error occurs
    Application.Run "ATPVBAEN.XLA!Regress", ActiveSheet.Range("$e$10:$E$" & yLast), _
    ActiveSheet.Range("$d$10:$d$" & xEnd), False, False, , "Analysis", False, False _
        , False, True, , False
    ActiveSheet.ChartObjects("Chart 1").Activate
    ActiveChart.ChartArea.Select
    ActiveChart.Location Where:=xlLocationAsNewSheet, Name:="Chart1"
    Sheets("Data Summary").Select
    ActiveWindow.ScrollRow = 1
    Range("G10").Select
    ActiveCell.FormulaR1C1 = "=SUM(Analysis!R17C2+RC[-3]*Analysis!R18C2)"
    Range("G10").Select
    Selection.AutoFill Destination:=Range("G10:G99"), Type:=xlFillDefault
    Range("G10:G99").Select
End Sub

Any help would be greatly appreciated.

Is there a specifc reason why you are using the 'Application.Run' syntax?

[vba]Application.Run "ATPVBAEN.XLA!Regress", ActiveSheet.Range("$e$10:$E$" & yLast), _
ActiveSheet.Range("$d$10:$d$" & xEnd), False, False, , "Analysis", False, False _
, False, True, , False
[/vba]

I'm pretty sure that if you want to pass Objects to a subroutine, you need to call it as a VBA Sub.

[vba]Regress [Range Object], [Range Object], False, False, , "Analysis", False, _
False, False, True, , False[/vba]

I don't see where you're putting a value into yLast. I think you meant yEnd?

[vba]
Range("$e$10:$E$" & yLast)
[/vba]

Actually, it does not seemed to be Dim-ed. Did you use Option Explicit at the top of your module?

That still won't work, since yEnd is a Range. Your probably want yEnd.Row since you're making a address (string)

[vba]
Range("$e$10:$E$" & yEnd.Row)
[/vba]

will give something like Range("$e$10:$E$1000")

Dr. K

To answer your question, the syntax for the regression came from a recorded macro. I took this as a shortcut.

Thanks. That did the trick. Sometimes the answer lies in the basics and I get wrapped up in the code and forget the simple things.
