Dynamic Formula put in formula with VBA

[aguice]

I have VBA code creating X number of weeks in columns. Each week consists of M-F(Columns 1-5), and then a total of that weeks numbers(Column 6). And then say X = 2, I would have a 'Grand Total' in Column 13. Column 6 and 12 have totals from M-F(got that formula from Selection.FormulaR1C1 = "=SUM(R[0]C[-1]:R[0]C[-5]"), but then I need a formula to put in Column 13. The formula for X = 2 would be this, "=SUM(R[0]C[-1],R[0]C[-7])". How would I write the formula so that it will change with X. (ex. X=3, "=SUM(R[0]C[-1],R[0]C[-7],R[0]C[-13])" )

Any and all help is appreciated!

Where does X come from? How does M-F make 5 columns?

An example would make it all clearer.

X comes from a user inputbox that pops up and the user puts an integer in the text field.

The actual process is making all 7 days of the week for each week, then converting saturday(using a weekday(currentcell) = 7) to be the column for M-F totals. and then deleting the sunday column.

After the loop is done with all X, I have just a line of code labeling the last necessary column as "Grand Total". And then need a way of creating the formula to write in that column to get the 'sum of the sums'(sum of the weekly totals).

I am new to this forum, can we post files up here? or what kind of example you looking for?

You can post files. Use the Go Advanced button, then manage files. Talk through an example with that workbook data.
