I have taken a look at your example but I can't figure out where the drop-down menu is intended to be or which data it is intended to return. It doesn't look like the price and description data has been included in your example?
It may be that all you need is a simple filter. You can see how to use these in the video lesson: Expert Skills Lesson 1-3 Apply a simple filter to a range.
If this isn't the solution, you may wish to use a list validation instead. These are explained in the video tutorial: Expert Skills Lesson 2-11 Add a table-based dynamic list validation.
There's also the possibility of using a combo box form control. This isn't often used, but you can see how to use it in: Expert Skills Lesson 9-2 Add a combo box control to a worksheet form.
From your description, it sounds like you will need to use a VLOOKUP function to search for the room that matches your selection and return the description and price. You can see how to do this in the video lesson: Expert Skills Lesson 3-22 Use a VLOOKUP function for an exact lookup.
I hope this helps, but if you can attach an example that includes some example data I should be able to provide an example solution for you, and please feel free to reply if you have any other questions.
