In fact, when I use the "run" option on the BB editor, it points to the
line

FLSdata!Range(Cells(k, "A"), Cells(k, "O")) = RAWdata!Range(Cells(i,
"A"), Cells(i, "O"))

and says "run time error 424: Object required"

What does that mean?

I tried changing that line to:

FLSdata!Range(Cells(k, "A"), Cells(k, "O")).Value =

RAWdata!Range(Cells(i, "A"), Cells(i, "O")).Value

but keep getting the same message. (Please note that the code just
before this line which is exactly similar in logic gives no error).

Thnx,
