entering hours into form but break time is having format issue

[Karaline]

Hello I have a form and i am entering
starttime
breaks
finishtime

i had it set to date/time but it wouldn't calculate. changed the breaks to number and it calculated, but when i enter the breaks it looks as if it is a whole number and entering 4hours and 75 minute break is not possible without doing manual calculation first.
Help is appreciated.

Well, if breaks was date/time, you'd have to enter a decimal value, or format the textbox as time so it would get interpreted correctly. One way or the other you're going to have to calculate, so you just need to decide. I'd probably have the start and finish as date/time, and the break as a number (minutes), but it depends on how you want to enter.

i have calculation set up and all is working (kind Of) because the break format is showing 75 minutes as 75.00 it is causing issues if I have to enter a break of 2hours and 20 minutes.
=(DateDiff("n",[Start],[End])-[Breaks])/60
how do i fix the format of the break field? can't find an answer specific to this on google. my formula works until i need to enter hours into break total.

StartTime	Breaks	FinishTime	VStart	VFinish
11:00		17:30	0	0
14:00	0.00	15:30	0	0
7:00	110	16:00	0	0
10:00	0.00	11:00	0	0
7:00	0.00	10:10	0	0
	0.00		0	0
	0.00		0	0
	0.00		0	0
	0.00		0	0
9:15	24	16:15	0	0
7:00	90		0	0
7:00			0	0
9:15	47	16:15	0	0

Without knowing how you are entering the date/times and the break time, it is very hard to give a good answer.
Do you have a picture of the form? Can you post the dB?

Do you have a control for the start time, a control for the end time and a control for the break time in hours? In minutes?
Two controls: 1 for hours and 1 for minutes?
More that 3 controls? How many controls/breaks?

If you had two controls (hours and minutes), you could enter in 2 hours and 30 minutes (NOT 2.5 hours), convert to minutes and calculate the total break time in minutes so you wouldn't have to manually do the calculation. You could enter 0 hours and 90 minutes (instead of 1 hr and 30 min) and still get a valid number.

Say the start time is 8am and the end time is 5pm. There is a 1 hr lunch, a morning break of 15 minutes and an afternoon break of 15 minutes. That is a total of 1hr and 30 min.
Are you calculating [end time] - [start time] - [break time]??

Will try and explain again.
I have a start time
06:00 perfect enters correctly
Finish time
18:00 perfect enters correctly
Breaks enter as an hour time if you have a 30 minute break you would enter as below
0.30 Perfect BUT when you click tab to go to finish Time it changes the look and turns into 30.00

now that is a problem because if i have to enter total breaks due to breakdown as 2 hours and 45 minutes i have to multiply 60 x 2.75 to get the number to enter.
i then have to enter into the form cell as
1.65 it then turns into 165 when i leave the cell.

this isn't answered in above link.
Please help this has been an ongoing issue for a month and i need to solve it today.
Actually working on a Saturday on my own time to solve this issue.

See attached dB for one way to do the calculations.

One form uses "Query1" as the record source. "Total Hours" NOT saved to the table.
One form uses "Table1" as the record source. "Total Hours" is saved to the table.

Thanks Steve,
Will work. will change the table to store separate fields for hours and minutes. i am sure there is another way but i am happy with anything. Thank you so much...
It is 9:10pm Saturday night. I am pushing it but need to get the queries finished by Sunday morning.
I will change the forms.
I don't store any calculations in tables.
