hi,

i have a cell in sheet_new with a formula in cell A1:

= sheet1!C2

i would like to know how the cell A1 can keep this formula even if sheet1 is
deleted, because it may be possible to delete the sheet1 and later add it
back, so when it is added back, i want the formula remembered/restored.

thanks in advance,
geebee
