data entry form in access

I have 2 tables, 'contact list' & 'transactions', and every few months people in the contact list pay their fees.  What I would like to do is have a form that shows everyone in the contact list with blank fields from the transaction table so that I can enter transactions for the ones that have paid.  My tables are structured as detailed below.
Contact List - pID, First Name, Last Name
Transactions - ID, pID, Date Paid, SessionNo, ChequeNo, Amount


I attach a stripped down version of my DB.

I downloaded your database, and don't see the form you're referring to. While we don't mind helping you achieve your goals, we aren't here to do the work for you. Instead, we'll help you when you run into something you can't solve yourself.

I would assume you could create a Mainform/Subform sort of setup to achieve what you want. First, create two forms - one based on the ContactList table, and another based on the Transactions table. Embed the Transaction form into the ContactList form, and link them on the pID field. From there you could locate a Contact using the navigation buttons, and enter a Transaction in the Subform. If you setup the linking correct between the Mainform and Subform, Access will handle the data relationships for you, and insert the records in the correct table.

Thank you Scott/Rey

Yes, I understand your comments and I certainly do not expect you to do my work.  I should have explained that I already have a form/subform scenario, but I was wondering if it would be possible to have a situation where the existing contacts all show on the same form with blank columns for the transactions.  See my basic concept attached.

You could create a query that includes both tables, and try using that. You would see only a single "new record" line, however, and data entry would be challenging, to say the least.

You could perhaps use a temporary table setup, where you create a table much like the layout of your Excel file and fill that table with data when the form is opened, then base a form off that table. With this sort of scenario you could add "new" lines for each record in the Contact list, and the user could interact with those. When the user closes or saves the data, you'd have to write code to move their changes back over to the live tables.

However, that sort of interface would still be somewhat "klunky", it would seem, and what happens if I need to add two transactions for a single Contact? I'd have to have some way to select the correct Contact, and then you're back to square one - how do you enforce that relationship?

Thanks for the additional comments, Scott, I have taken them on board and agree that it will be a clunky solution, so I think I will add my data in excel, then create a linked table with an append script to add to the transactions table.
