Copy formulas of previous row if values are filled in column A

Dear Friends,

I have a worksheet, called monthlysheet, in which cols. A - CX are there.

Assume that I have right now data from A4 - CZ104 (Row #3 is my header data).

From Col.A to Col.BZ are my values
From Col.CA to Col.CX are formula based columns.

Now, if i copy 50 data from some other workbook to this monthlysheet in cols. A - BZ, then I want to copy the formulas (all available in row #104) for the copied 50 data also.

i.e. if values are copied in Col. A then automatically the formulas in Col.CA to CX should be copied for the same number of copied data rows.

I need a VBA to automate the process.

Thanks & regards.
