Hi all,

I currently have a excel spreadsheet set up to take the following.
Just an example:
Cell A1 - Time Started (In 24 hour time) - "06:30"
Cell A2 - Break Time (Generally Half an hour) - "00:30"
Cell A3 - Finish Time - "16:30"
Total - =(A3-A2-A1)*24 Which gives me a result in hours which I wanted. "9.5"

However When entering in the break time I want to be able to enter it in as
.5 (for half and hour) instead of having to enter in 00:30 for 30 minutes and
still calculate the correct response at the end.

Also, i'd like to be able to enter the times in without having to enter the
: in, for example "0630" (starting at 06:30) and "1630" (finishing at 16:30).

Could someone please let me know whether the above is possible, and if maybe
you have some suggestions for cleaning it up it would be appreciated.

Regards,

Ricardo
