Graham,

If what you are asking is how do you subtract an integer in say B2 like 90
from a time like 14:00 in C1 then try:

=$C$1-(B2/60/24)

and format column C as time

In Excel 2000, I want to create a spreadsheet which has a column of foods,
a column of cooking times (in minutes), and a third column which
calculates the time to begin cooking that item based on an inserted
mealtime. For instance, if a mealtime of 2:00 pm is inserted manually then
the row for "Beef Joint - 90 mins" would return 12:30 pm in the third
column; and the row "Carrots - 30 mins" would return 1:30 pm in the
third column. I think the answer is in the formatting but I cannot make it
work!
