trying to create a scheduling doctor appointments in Access 2013

My boss asked me to do a new Access database from scratch. I’ve never done an Access database on my own before, and would appreciate any advice you guys have. This is to help employees schedule appointments for 46 medical doctors in 14 different medical offices.

As for my relationships, I hope I’ve set up everything correctly:

As you can see, I’ve set up two junction tables, but am not quite sure how to set up a search query with junction tables. I’ve looked in my two Access 2013 books, and I’ve also looked online but am not having much luck. For example, with the table Junction_Provider_Insurance, I’m not sure how to search the Junction table to pull up the doctor and if the doctor is contracted, not contracted, needs authorization or pending for the insurance. So if a doctor’s name and an insurance name such as Aetna is searched, I want the result to show that the doctor is or is not contracted with Aetna in ReportResults.

As for the search, I originally set up a wildcard search for all the search boxes. My original intention was that the user could type in anything they wanted in one or two or three of the boxes (such as doctor’s name, visit type and insurance) and do a search where the results come up. However this is not working at all and time is of the essence as I’ve already missed my deadline to turn in this a week ago.  

Due to missing the deadline, I decided to change the wildcard text search to a combo box for the Doctor’s Name, Medical Office Name, Visit Type, Specialty and Insurance in the hopes the search will finally work. I’m thinking the best way to handle this is to remove the medical office, and then just have the doctor’s name, then when that comes up, to cascade into a new combo box for the visit type (new patient, follow up, pre-op, post-op, etc.) Or is there a better way to do this? I still need the results to show in the report too.

Thank you so much for your time and help. I really appreciate it very much.
