DaniWeb IT Discussion Community - Need help with overload functions

Ok I have everything pretty much working except for one small detail. When I do inpatient I need to display the room charges as well as the medication and labs and services. It only displays the medication and labs and services charges but in the total includes the room charges, but is not showing them.

Thanks.
