Displaying text from another worksheet

Hi all,

My first post here.

I'm doctoring an existing spread sheet (downloaded from the internet) for booking IT equipment at work. There are two tabs, booking and availability. In the bookings tab the user will enter the dates and equipment they wish to use. Does anyone know how to pull the text from the E column of the bookings sheet so that it is displayed in white text on the corresponding booking in the availability sheet?

There is already a formula in the cells of the availability sheet that blocks out the booking in red. I can't work out what or where to add in order to display the text.

Thanks in advance.
