Excel HELP! Exam reservation system?

[FatmaMS]

I am creating an excel workbook for an exam reservation system.

In my workbook, I have a sheet (Exam sheet) that has a table of previous and future exams that contain the following fields: Room Number, Date, Time.

I also created another sheet (Exam reservation) that asks the user to input the Room number, Date and Time.



I want a cell that outputs if the room is available by searching through the exam sheet and checking if there is an exam at the same time and date in the room the user specified.

I don't know which excel function could do that.. Thanks for your help

Alright, sorry about that.. there are many other sheets that are quite irrelevant to my questions.. I attached the excel sheet..

The excel file suggests a recommended room based on some other things.. Given the recommended room and the date and time in exam reservation sheet.. I need to check whether the room is booked or not as per the entries in the exam sheet.. I thought I need a lookup function.. but then I have to check for this room number.. if there are matching dates and times..

I hope my question is clear
Thanks a lot
