How to count completed tasks on canvas column

[Piet_Strydom]

Hi Gareth

I have given an example here:

Help linking a formula in parent table column to a canvas column

HI Gerardo, Sorry, sometimes I make wild assumptions… Below is a link from the main table, to a table on the canvas. In practical terms, the formula reads the Attendees table which is on the canvas of the canvas column, and count the number of attendees for each meeting. (Take care to select the table, and not the row specific view. If you choose the latter, the formula will only work for that particular row of the meetings table, and not all the other rows as well. Just replace count()…
