HI!In order to count the number of unique values in a column that have the same corresponding value in another column you can use this formula in google sheets : =ARRAYFORMULA(SUM.IF(C2:C;UNIQUE(C2:C);E2:E))

Have you tried to link the tables with an ID COLUMN and then activate the “interactive mode” of the Dashboard view ? Usually it works!

To solve it I used the formula ANY(FILTER(…)) in the initial value of the ref column.

Congratulations @GreenFlux! Great Work !

HI ! @Lucinda_Mason I never tested it, but I think it’s possible only with an external service like Twilio and sure you can do that only with a deployed app.
