I tried this code which worked as far as opening the excel file but failed to activate the specific worksheet
Sub OpenExcelFrom Word()
Dim oExcel As Excel.Application
Dim oWB As Workbook
Dim oWS As Worksheet
Set oExcel = New Excel.Application
Set oWB = oExcel.Workbooks.Open("C:\Users\aacce\Dropbox\Documents\1-WW6\PORT-full-2.XLS")
Set oWS = oExcel.Worksheets("Cost").activate
oExcel.Visible = True
End Sub
Sub OpenExcelFrom Word()
Dim oExcel As Excel.Application
Dim oWB As Workbook
Dim oWS As Worksheet
Set oExcel = New Excel.Application
Set oWB = oExcel.Workbooks.Open("C:\Users\aacce\Dropbox\Documents\1-WW6\PORT-full-2.XLS")
Set oWS = oExcel.Worksheets("Cost").activate
oExcel.Visible = True
End Sub
