copy the code from the answer you got and paste it, Bob's example is using
the range H1:H10, you can change that to whatever you want the range to be

you need a macro to get this conversion done or you can use autocorrect and
replace a period with a colon

Is there a way to be able to type it in a number (i.e. 11.45) and have
it
display as a time (11:45)? When I format the cell to display as time I
have
to type the hour, a colon, and minutes. Is there any way around this?
