In Excel97, I have the following times i would like to sum.

8 41:33:81

If i sum, i get 41:33:81, but the correct result for
this case is 42:53:81 (Minutes:Seconds:Seconds/100).

I would like the result to be in one single cell,
that in this case is cell A8.

What formula should i write in cell A8 ?

Any Help appreciated.

Robert.

You could use the array formula:

=SUM(--("0:"&SUBSTITUTE(A3:A15,":",".",2)))

and format as [m]:ss.00

or if you really want colons as separators throughout

=SUBSTITUTE(TEXT(SUM(--("0:"&SUBSTITUTE(A3:A15,":",".",2))),"[m]:ss.00"),".",":")

In the latter case, the result will be text and not a number that Excel can
manipulate.

To *array-enter* a formula, hold down <ctrl<shift while hitting <enter. XL
will place brackets {...} around the formula.
