You cannot use formatting as an input mask to enter times or dates without the
proper separators.

Use the colon or see Chip Pearson's site for entering times/dates using VBA
event code.

OR Bob Phillips' site for an add-in for Quick Date Entry.

PLEASE HELP! I have used the 00:\00:\00 format to input times without having
to press the colon every time. Now though, when Excel tries to minus one time
from another, because of this formatting it only recognises times as numbers,
e.g. 12:15:30 - 12:14:50 Excel thinks this equals 00:00:80 !! Can anybody
help?! How do I get it to recognise that the answer is 00:01:20 ??? thank you
