Calculate whether time is between two #'s

All,

This place has been a great help to me in the past 6 months or so, so I'd like to start by thanking everyone for their help.

Scenario:
1. I have the following Dates and Times: ETA and Arrival
2. I have calculated the difference between the two resulting in [h]:mm

Example:
ETA = 4/2/2013 14:00 (A1)
Arrive = 4/2/2013 19:51 (A2)
Calc Difference = 5:51 (A3)

Challenge:
I am trying to determine if the difference value in column/row A3 above falls within a certain period of time. So for example, does A3 above fall between 2 and 3 hours? If so, Yes, if not, No. Then in A4, we would be moving onto 3 and 4 hour time window with same results, continuing to repeat in the subsequent columns.

Can someone help me with this? It seems straight forrward but there is something with the formatting that appears to be causing me issues.

thanks!!!!!

Ok I think I may have gotten it to work.

=IF(AND(A3>=--"2:00",A3<=--"3:00"),"Yes","No")

Sound right?

Well that didn't work as you can see below:

ETA - ATA Time Difference 2-3 hours late
2:00 No
2:00 Yes
2:00 No
2:00 Yes
2:00 No
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 No
2:00 Yes
2:00 No
2:00 Yes
2:00 Yes
2:00 Yes
2:00 Yes
2:00 No

I like the idea, but it doesn't look like it worked. See below

ETA - ATA Time Difference
5:51 5-6 hours
288:01 0-1 hours
0:00 0-1 hours
43:16 19-20 hours
0:00 0-1 hours
0:00 0-1 hours
3:20 3-4 hours
0:09 0-1 hours
20:00 20-21 hours
16:00 16-17 hours

that should work. thanks!

Ok, last question

So now I need to count and report on trends. The above is working well, but I'm not sure it's relevant to count individual hours beyond a certain timeframe.

So how would I could all those that came back beyond 24 hours? Right now I am counting based on specific returned results
=COUNTIF($AB23,"0-1 hours")

If I wanted everything beyond 24 hours would it look like this? I doubt it, but not sure where to start on this one
=COUNTIF($AB23,"24-**** hours")

cool. the formula only returns the hours, not the minutes (e.g. 5 instead of 5:51), but I think I can still work with this. thanks so much!
