SOS HELP ME!!!!!! – Hotel Tycoon 2 Review

Does anyone know how to scroll up and down on the options when building a standard hotel room? I'm unable to scroll, and therefore unable to build my first hotel room because it requires a TV, bed, night stand, ect. However, I'm unable to scroll to the TV options!! Sos!!
