Hi,
first, you should get rid of the merged cells on sheet 2. They can lead to all kinds of trouble. Use the horizontal alignment option "Center acoss selection" on the Alignment tab of the formatting box instead.
What is the rule behind how many hours should be yellow, how many green, how many blue? This does not come from your data, as far as I can see. You'd need to give Excel something to work with.
Oh, and the formatting for the break time is using borders. These can not be set with conditional formatting, but the background colour should be fine, as long as there are only three conditions.
So, can you give us a bit more info?
