You forgot to quote the relevant bits of the message to which you were
trying to reply, but if you want to convert 8:30 to 8.5, multiply by 24 and
format the result as general or number, not as time.

Ok..., this works. Thanks.

In order to make calculations, i.e. sum totals of the product cells,
we need to keep the formats in time, i.e. 8:30 + 8:45 = 17:15 . What
I'm trying to do is convert the time formats into number formats. So
that total time 8hours and 30 minutes (8:30) results in a number 8.5.
