Difference of two text boxes into a third text box

[beckie1234]

I have two text boxes that show a begin time and an end time. I want to take the different and put it in another text box that shows the results.

EX:
begin end total
05:12 am - 05:23 am = 11

Any suggestions??
I am looking to make it so whoever does data entry, it will be a little easier because the total will be automatically be entered into a text box.

Look up DateDiff() in Access help. Obviously the 2 time fields will need to be formatted as Date/Time and not just Text

Col

They are formatted as time. I looked through the different examples and it show how for format date/time and minus dates from other dates but I need it to specifically subtract the first time from the second time and display the results in another text box. I understand that is where I would put in the formula just not sure what it is.

Set the control source of the text box to:

=DateDiff("n",[Begin],[End])

this will give the difference in minutes between the two times.
