I need to be more precise:

I have a 3 sheets workbook: 1 Main, and the other 2 are to input the data.
At the end of the day, when all the data is input in the 2 worksheets, a
button is pressed and this button will start a macro which will select all
data, copy it, open the sheet calle main, paste the cut data in the first
available empty place and then delete the data in the workbook. Only 1 cell
per row in this worksheet has a formula (i.e. =H2 - E2). When the macro
deletes all the data in the input sheet, it also deletes the formula... how
can I prevent it from happening? is it possible to create a macro or a code
that will restore the formula in the given cell(s)?
