NEED HELP! Code that checks all data has been entered before my VBA Macro Runs!

Hi guys,

I have the following macro which allows you to enter a row of data (Only one row will be visible), then you press a command button and the row of data is inputted into another work sheet.

* I would like a way of ensuring that Excel checks the whole row of data has been filled out before allowing itself to run the following macro (which copies and paste all the data across to the other worksheet).

Here is the code I have so far. (Just to advise this macro starts on the "AddRecord" sheet.

Please someone out there if you can help me I would be forever grateful!!! :D

Sub addtoInboundWorkstack()
'
' addtoInboundWorkstack Macro
' Add record to Inbound Workstack
'

'
    Range("A3:I3").Select
    ActiveWindow.ScrollColumn = 2
    ActiveWindow.ScrollColumn = 3
    ActiveWindow.ScrollColumn = 2
    ActiveWindow.ScrollColumn = 1
    Selection.Copy
    Sheets("Inbound Workstack").Select
    ActiveWindow.ScrollRow = 45
    ActiveWindow.ScrollRow = 44
    ActiveWindow.ScrollRow = 43
    ActiveWindow.ScrollRow = 41
    ActiveWindow.ScrollRow = 38
    ActiveWindow.ScrollRow = 34
    ActiveWindow.ScrollRow = 31
    ActiveWindow.ScrollRow = 27
    ActiveWindow.ScrollRow = 24
    Range("A26").Select
    Selection.End(xlDown).Select
    ActiveCell.Offset(1, 0).Range("A1").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    ActiveCell.Offset(0, 9).Range("A1").Select
    Sheets("AddRecord ").Select
    ActiveCell.Rows("1:1").EntireRow.Select
    Application.CutCopyMode = False
    Selection.ClearContents
    ActiveCell.Select
End Sub

Happy Easter!
