Booking Calender - Lookup multiple bookings across date ranges for

Hi,

I'm trying to create a booking calendar in excel (attached), but having issues when I have bookings for different demos on the same date, it only shows as one demo booked out at a time.

So the front tab is the calendar, which looks up bookings from the booking form tab, and on there you will see multiple bookings for different demos and date ranges. Where date ranges overlap each other on the different demos, only one of the bookings appear on the calendar tab. I need to find a way to show all bookings on the calendar tab, so asking for advise as to how I can tweak my formulas to do so.

Can somebody please review and advise? Hoping this will be a simple task for someone as it's driving me crazy trying to fix this!

Thanks!
