Why won't target cell data changes trigger formula evaluation?

[laura_in_abq]

Why wouldn't the formula cells get dynamically calculated when target cell
data is changed? Couldn't find anything about this in help files.

I have been using this worksheet for years and never saw this problem... a
simple 2-week payperiod timesheet ... Fourteen pair of cells in which I enter
start time and end time, and fourteen cells with a formula to compute hours
worked per day (difference between the daily pair). Also weekly and biweekly
totals.

The cells all calculated when I "saved" the file. Also when I
closed/reopened, it still won't evaluate the formula cell(s) when I change a
"data" cell. Only if I hit "save", or individually select each formula
cell, place the cursor in the function box, and press enter.

1) What happened?
2) What can I do to fix it.
3) Is there a command that I can run to "calculate all" functions in a sheet
(or workbook)?

Look at "Change when and how formulas are calculated" in the help file.

Sounds like you just need to go to Tools> Options> Calculation tab and click
the automatic radio button.

You have changed calculation from automatic to manual with "calculate on
save" enabled.

This probably came from another workbook that you opened prior.

Excel takes the calculation mode set in the first workbook opened in a
session and uses that mode for all subsequent books being opened.

Make sure you save your workbook in aut0calc mode and don't open a
manual-calc workbook first.
