start time (A), the other is duration time (B).
have in this column is =sum(F:15:G15)+TIME(0,1,0).
This adds the time in column B to the time in column A,
plus one minute

Then why is your formula referencing column F?

Why don't you just format as General (or Number, 0 decimal places) and enter
it as an integer 130?

Then:

=SUM(A15,B15/1440,1/1440)

I have two columns in my excel spreadsheet. One is start time (A), the
other
is duration time (B).

Start Time Duration
08:00 15
08:16 130
10:27 45

Start Time. I have formatted it to Number, Custom, [h]:mm and the formula
I
have in this column is =sum(F:15:G15)+TIME(0,1,0). This adds the time in
column B to the time in column A, plus one minute. Automatically
populates.
OK.

Duration. I have this column formatted to Number, Custom [mm], as I need
the duration time in minutes only. However, I can not enter 130 minutes
as
130, I have to key it as 2:10 (and it converts it to 130). I want to
actually key it as 130 though.

Not sure what to do next??
