Index / Match - desperation

[Kuba]

Hello to all,

Yet another wondering, as I fight my way through the INDEX / MATCH formulas.
THe macro copies (or rather aims to copy) the formula from coloured cells of one table, to the same relative position on another table.
When I use the following formula (as suggested yesterday)

For l = 5 To 2972
For k = 10 To 70

ThisWorkbook.Activate
Worksheets("DATABASE").Cells(l, k).Select
If Fillcolor(Cells(l, k)) = "-4142" Then
Else
With Workbooks(FileNameOnly(FMCFilenameOldRel)).Worksheets("DATABASE")
ActiveSheet.Cells(l, k).Value = _
Application.Index(.Range("db"), _
Application.Match(ActiveSheet.Cells(l, 9).Value, .Range("aletters"), False), k).Formula
End With
...... I still get the error message - but ONLY after it runs k up to 61.

If I get rid of the MATCH bit altogether (i.e. input row and column number from which to copy), the file runs fine (i.e. the INDEX bit seems to be ok).

Is it sth to do with the fact that I use a custom function FileNameOnly? How else could I reference easily between the two files: one that contains the macro and where the links (formulas) are copied to, and another one with the links to be copied from.

Merry Christmas, I hope Santa is good to everyone this year
