Mirror row deleting on multiple sheets.

Hi Guys/Gals,

I have a workbook used to create quotes for our client. On sheet 1 I have the "Cost" quote and on sheet 2 I have the "Sell" quote which basically mirrors the "Cost" Sheet, except for some calculations to add markup. I have a macro which inserts x number of rows above my last row(totals) on both sheets if more rows are needed.
Now what I would like to do is, if I delete rows on Cost sht, the same rows must be deleted on the Sell sht. Is this possible?

Regards,

Martin
