Hello:

I've written this macro (with a reasonable amount of support from this
group already) to copy data from several worksheets and paste it into
a "Master" worksheet. However, I've made a few changes to the
spreadsheet (rows for the header and a few additional columns) and
instead of appending data, it overwrites everything. How do I tell it
to go to the last row containing data?

Sub UpdateMaster()
'This macro updates the Master Spreadsheet, it is linked to a button
on the Reports tab

' Clears existing data on Master spreadsheet, except for header
row
Sheets("Master").Select
Application.Calculation = xlCalculationManual
Range("A3").Select
Range(Selection, ActiveCell.SpecialCells(xlLastCell)).Select
Application.CutCopyMode = False
Selection.ClearContents

' Copies data from each spreadsheet in the workbook, excluding
sheets named in Case, and pastes data in Master
For Each thing In Sheets
Select Case thing.Name
Case "Master", "Reports", "Test Filter", "ReportOutput",
"Diagram", "Master2"
'do nothing
Case Else
Sheets(thing.Name).Range("3:1000").Copy

Sheets("Master").Range("A65536").End(xlUp).Offset( 1).PasteSpecial
End Select
Next
Sheets("Master").Activate
Range("A3").Select
End Sub
