[Saritha123]

I want to copy column 'Q' of sheet 1 to column 'E' of sheet2, if that value not already present in column E of sheet 2.
Sheet 1 values starts from Row 5, Sheet 2 values starts from row 7.
Dnt want to copy entire row, but only want to copy the column values using VBA macro.
Please help.
