I've having some trouble understanding how to do this Error Handling thing.
Any assistance that's offered is greatly appreciated! My coding is at the
end.

The macro is opening a series of files, manipulating them, then resaving
them with a new name. The file names and manipulations are all listed in a
spreadsheet; the macro pulls one row of information, does its thing, then
moves on to the next row until it reaches its stop command.

Where I'm having trouble with the error handling is getting the macro to
continue on its way after an error (if I understand correctly what's going
on, it actually is continuing on its way, but then stops upon reaching a
second row with an error)

My goal is to have any errors put a message in a cell of the offending row,
rather than a pop-up message. There's actually a couple loops in the macro,
my thought is that I can put in several "on error goto" err_handler1,
err_handler2, etc., and have each err_handler populate a different message.
Depending on the step where the error occurs, I can then populate that cell
with a message that instructs the user what correction is necessary.

So here's the coding I was using on the first loop. Thanks in advance for
any help!

Do Until Grow = NextRow

Windows("Personal.xls").Activate
Sheets("Info Delivery").Activate

If IsEmpty(Cells(Grow, 28)) = True Then GFolder = Cells(Grow, 27)
Else GFolder = Cells(Grow, 27) & "\" & Cells(Grow, 28)
ChDir SourcePath & GFolder

If Cells(Grow, 41) = "Y" Then
Application.EnableEvents = False

On Error GoTo Err_Hdler1
Workbooks.Open Filename:=SourcePath & GFolder & "\" &
Cells(Grow, 33)
Application.EnableEvents = True

End If

Err_Hdler1:
Select Case Err.Number
Case Is = 1004
Range("F" & SummaryRow) = "File Not Found"
Case Else
Range("F" & SummaryRow) = "Unknown Error"
End Select

SummaryRow = SummaryRow + 1
Grow = Grow + 1
Loop
