I am very new to Access and any help would be appreciated. I have been through the entire Access Bible and many forums but can't find the answer to my specific question.
The project:
I'm setting up a database for tutors and students. Tutors will, via the web, enter data about a specific tutoring session (studentName, subject, sessionLength, etc.) Then at the end of the month a report will be generated detailing hours tutored and total compensation.
The problem:
Students pay varying rates based on subject (math or verbal). So in the Session table each record for each tutoring session has an empty field called payRate. This is the rate the student will pay based on subject. So I need this field to "fill in" automatically based on the 'student' and the 'subject' from the same record. Then I can multiply the field by sessionLength and get a totalPay field for the session. Add these at month's end and pay the tutors.
I've set up a lookup table called 'subject' with three fields (student,subject, payRate) and I have the student and subject combined as the primary key. Am I on the right track here? If so, how do I link the tables to get that Session 'payRate' field to fill in automatically. This is where is breaks down for me. I've tried the lookup wizard but all I seem to get when I open the Session table is an empty PayRate field with a drop down box containing the entire subject lookup table.
Sorry for being so long winded but I need help from someone better at his than me. Thanks in advance.

I'm wrestling with the issues; in other threads, it became apparent that because I could not know ahead of time what I will need to know about a given entity, I will use a table to enumerate attributes that is applicable for a given entity.
However, the stumper is that what if an attribute should conform to a set list of values? Since they are dynamic, I would have problem predicting what I will need to be able to lookup, and am even don't know whether I will need a one-many lookup or many-many lookup.
I thought that generic lookup table with a table listing "classes" of lookup would allow me to have one big generic lookup table while using "classes" to act like virtual tables so I can then set the query to appropriate "class" to return just right set of values.
But as I thought about it, I ran into some issues which is pulling me toward the crazy idea that I should have freestanding tables, and use a field in tblAttribute to give me the table's name so I'd know which free-standing table it points to, and have the necessary key to lookup the values within that table.
Even though my gut instincts tell me that I shouldn't be going against the conventions of database design (who the frick goes around creating free-standing lookups?!?), I'm simply not sure how I can use a generic lookup table to hold all information.
For example, suppose I was given a list of values that has its own categories. Since the former design allows only for two level (lookup and lookupclass), where am I to insert that extra level?
Furthermore, I found myself needing a set of virtual keys to reference a certain "class" of lookups for report purposes. That means I need an extra field in my lookup table than I originally anticipates. What if I find myself needing one more field that just won't fit the generic lookup table?
So does anyone have suggestions on how we would create a placeholder for a lookup table that will be made just in time?

BACKGROUND
I am desperate to solve this problem but unfortunately I have not been able to figure it out. Below I will outline a design of a database and the desired results.
I know what I want to do but I don’t know how to do it (or whether it is impossible!)
DATABASE DESIGN
The design below is a simplified version of the real thing but it contains the essential information needed to understand my database.
Staff Data
Contains daily data for several members of staff
Staff ID
Staff Name
Date
Data Field 1
Example records:
600-001, Bob Smith, 01/03/2006, 50
600-001, Bob Smith, 02/03/2006, 50
600-001, Bob Smith, 03/03/2006, 50
600-001, Bob Smith, 04/03/2006, 50
600-001, Bob Smith, 05/03/2006, 50
600-002, Jayne Cole, 01/03/2006, 60
600-002, Jayne Cole, 02/03/2006, 60
600-002, Jayne Cole, 03/03/2006, 60
600-002, Jayne Cole, 04/03/2006, 60
600-002, Jayne Cole, 05/03/2006, 60
600-003, Alex Winter, 01/03/2006, 20
600-003, Alex Winter, 02/03/2006, 20
600-003, Alex Winter, 03/03/2006, 20
600-003, Alex Winter, 04/03/2006, 20
600-003, Alex Winter, 05/03/2006, 20
Team Lookup
Shows what team each staff member belongs to and what date this is effective.
Staff ID
Team
Start Date
Example records:
600-001, Sales, 01/01/06
600-002, Sales, 01/01/06
600-003, Accounts, 01/01/06
600-002, Accounts, 04/03/06
Please note:
The first three records show that at the start of the year Bob (600-001) and Jayne (600-002) worked for Sales and that Alex (600-003) worked for Accounts.
The last record shows that from 04/03/06 Jayne switched teams to Accounts
Query Assign Team
Assigns the correct team to Staff ID for each date
Staff ID
Staff Name
Team
Date
Data Field 1
Desired Results:
600-001, Bob Smith, Sales, 01/03/2006, 50
600-001, Bob Smith, Sales, 02/03/2006, 50
600-001, Bob Smith, Sales, 03/03/2006, 50

600-003, Alex Winter, Accounts, 04/03/2006, 20
600-003, Alex Winter, Accounts, 05/03/2006, 20
Query Group By Team
Summarises data by team/date
Team – Group By
Date – Group By
Data Field 1 - Sum
Desired Results:
Sales, 01/03/06, 110
Sales, 02/03/06, 110
Sales, 03/03/06, 110
Sales, 04/03/06, 50

Accounts, 03/03/06, 20
Accounts, 04/03/06, 80
Accounts, 05/03/06, 80
PROBLEM: WHAT I AM TRYING TO DO
I don’t know how to get the query “Query Assign Team” to work!!
I would like to lookup up the ‘Staff ID’ and ‘Date’ in “Team Lookup” and return the appropriate value for ‘Team’
If the only two records in Tbl Staff data were:
600-002, Jayne Cole, 03/03/2006, 60
600-002, Jayne Cole, 04/03/2006, 60
I want the query to return:
600-002, Jayne Cole, Sales, 03/03/2006, 60
600-002, Jayne Cole, Accounts, 04/03/2006, 60
Can anybody help me?
Should I be using DLOOKUP? If so, how?
Is VBA the only way around my problem? If so, can you tell me what it is?
Am I attempting the impossible?
