Date/Time Comparison

Having problems getting the following scenerio working.
I am needing to compare a date specified in cell (x) with "NOW" and if it is greater than 10 minutes enter "2" in cell (y).

Attached is a example of what I am looking to do, it is a bit flacky on the calculations of time but I think you can determine what I am looking to do.

What needs to happen is if it is an "Urgent" and in "Work In Progress" and has not been modified for 1 - 2 days enter "2' in column P. If it is in that status for more than 2 days then enter "3"

Also will need to do the same type of thing for tickets that are not urgent but have not been modified for 10 minutes.

Any help would be appreciated.
