Hello, I'm building this database for an assignment at school. I'm executing the following code in blocks. I have executed blocks 1,2,3, and 4. Block 5 gives me this error though:

Msg 1767, Level 16, State 0, Line 1Foreign key 'FK_apptId' references invalid table 'appointment'.Msg 1750, Level 16, State 0, Line 1Could not create constraint. See previous errors.
I am using MSSQL Server 2008 R2 Any suggestions? Also if you have any recomendations I'd appreciate it. Thanks for your help block 1

That error message would come from block 6, it sounds like you didn't run block 5. Look at the error: Foreign key 'FK_apptId' references invalid table 'appointment'. Block 6 creates FK_apptId, and if it says there is no appointment table then it sounds like you didn't run the code to create it.

There is already an object named 'FK_patientId' in the database.
That one should be self-explanatory. It doesn't create the appointment table because it has a constraint with the same name as one that is already there. This error:
Msg 156, Level 15, State 1, Line 16Incorrect syntax near the keyword 'CONSTRAINT'.
Is because of an extra comma before that line. This error:
Msg 156, Level 15, State 1, Line 4Incorrect syntax near the keyword 'create'.
is because of these lines: create table insurancecreate table perscription(
