Hi

I am running a macro In Excel 2003 Profressional that iteratively opens up a
list of spreadsheets and copies and aggregates the data. I recently started
receiving the Run time Error shown above. The code that blows up is shown
below. What is odd is that
a) it works the first few times
b) it is calling a Macro that works all the time
c) after the error, Excel is totally useless, you can't see the cursor
move,...

PLEASE HELP!!!
Thanks

For R = 1 To rowstoadd
Application.GoTo Reference:="RRcopy_to"
Selection.EntireRow.Insert
Range("RRcopy_from").Copy <==== ERROR <====
ActiveSheet.Paste
Next R
