Need a help with the records calculation&

[Costas]

Hi everybody!

I'm a novice in file maker. I've tried to find info about records calculation but no success.

The problem:

I have field1 with the following records - FFA, FFA, TTA,TTA,TTA. And I want to create a field which in every record will show how many such a kind of records I already have. (Sorry for my English)

I try to show:

Field1 Field2(will show a result)

FFA 1

FFA 2

TTA 1

TTA 2

TTA 3

Thanks a lot to everybody!
