Adding function without messing up original code

[peter renton]

Hi I have attached a copy spread sheet.
This has been working great but i have been asked to add some items and i dont want to screw up the working functions.
I now want to add a columns so the actual costs of a first and second service can be added to the contracts and used contracts sheets,
this information allong with cutomer,reg,start date needs to be copied over into a new report sheet which will have the budgets costs in so that
a report can be sent showing profit/loss.

If i just add columns will this effect the auto archive coding?
Could the data be copied over to the new sheet using the original code on start up? (so customer etc copied then as cost are put in these would be added
to the respective rows on each start up.

I hope i have explained this ok ?

Regards

Peter
