One way would be to create a third entry for Jack with a negative 50. That way you can still sum the table.

Is it really about what you want or what the best solution is?

You should already have all the payments stored in a table so all you do is prefix it with a minus sign and run a SUM totals query.

Unless you mean that you want calculations calculated on the fly when the user enters 50 as payment. Perhaps you should properly explain what you're trying to do and where you're trying to do it.

You can achieve this in a number of different ways. You could perhaps extend your existing table to include a "category" (id) column so that your "price" column accommodates positive and negative values. I.e if you have a category of "deposit" and another category of "withdrawal" you can fairly easily maintain a balance.

This isn't a VBA question, it relates, pardon the pun, to your underlying table and query design.
