Trying to open a Workbook and a run a macro in that file

Question

I have a workbook which opens up another workbook (filename is based on a cell value) and then runs a macro called Single_sector within that file.

It opens the file

Answer 1

Place the following code in the macro calling the other workbook:

Location = Worksheets("Main").Range("folder_location").Value
Set wb = Workbooks.Open(Location & Range("fv_file").Value)
Application.Run "'" & wb.Name & "'!" & strSubToRun, Parameters
Set wb = Nothing

Parameters is an array of arguments that you want to pass, so the sub in the other workbook should look something like

Public Sub TheSub(ParamArray X())

Dim i As Long

Sheet1.Cells(1, 1).Value = "Parameters passed:"

For i = 0 To UBound(X(0))
    Sheet1.Cells(i + 2, 1).Value = CStr(X(i))
Next

End Sub
