If statement and countif statement in an array

I am creating a shift schedule for my company. I would like to create a formula (using an array, I believe, is the only way to do this...but if there is another way I would love to hear it!) which will determine if the employee is entitled to a one hour lunch, based on the number of hours worked that day. The problem I am running in to is that the standard shifts vary (either 8 hour shifts or 10 hour shifts).

Basically, I want colum AJ "Lunch Hour" to know if the employee took a one hour lunch that day, based on the total number of hours they worked (AH) and their standard shift (AI). I want it to show a "1" in AJ when the standard shift is 10 hours and the person worked 5 or more hours (you don't get a lunch if you work a half day) OR if the standard shift is 8 hours, then they only get the one hour lunch when they work 4 or more hours.

The way I have the AJ colum calculating now, it cannot distinguish between people who worked a full day and people who worked a half day.

I am using Excel 2007, but I have uploaded a 2003 compatible file to this post.
Thanks!!
