without knowing what you are refering to we cant really help!, what is the error? have you got your cells address correct i.e Cells(RowIndex, ColumnIndex)

i'm really sorry the unclear message, correct the col G & H value are number format that actually is time,
want to calculating the different time by col H - G and for convert to 00:00
don't know it ok or not as i try built a macros for my worksheet.
