I have a bit of experience with Access and SQL but I'm new to Filemaker.

I have a layout which shows a list of projects. One of the fields I want it to show is "total amount of paid invoices up to the end of the last financial year". The invoices are stored on another table so I will need to pick from this table all records where "project id" = "project id" (this is set up as a relationship between the tables) and also "invoice is paid" = yes AND "date invoice paid" < start of last financial year.

My question is how do I go about getting and showing that data? I can get a total easily enough, it's filtering out these specific rows that I'm having trouble with. I'm guessing there's an easy solution...
