Ive got one I need help with.

In column B I have a piece of equipments id #. in D,F & h is where and for who. J is the date equipment was issued and L the date equipment was picked up. I have L set to highlight B to red showing the equipment has been picked up. In column T I have all the equipment listed as to be on the yard. What i'm wanting is to highlight the T column cell if the number is listed in column B and "NOT" highlighted red showing that it is not on the yard. Hope this makes sense. If anyone could help me on this I would appreciate it.

Thanks
