Calculating a field across multiple records

[Nomad Suit]

I'm a beginner with Filemaker. Assume I don't completely 'get' filemaker just yet, although I'm very savvy with Macs and a pro with spreadsheets.

How do I display a calculation of a field across multiple records?

Let's say I have a field that can either be 1, 2, or 3. I have ten records and I want to display, in the header, how many No. 3's I have.

How do I do this?
