I am more familiar with how I did my formula, but I think that the formula should be one key or another, not two different unique keys.
This is my understanding.
The other thing you can try, for your formula, type the first part, then after the equal sigh, use the Airtable mapping/value tag. Keep the quotes, though.
Try reversing the formula.
If you can explain a little bit, what you would like your formula to do?
Usually, this formula is going to tell Integromat, that if my unique key (a field that is always different), in Airtable, should be matched with the data coming into the scenario. Then once it matches the correct data, then it will place that incoming data into the correct record.
This is my understanding of this formula field.
I believe that this can be done, unfortunately, I don’t know too much about these functions.
I would suggest that you post this issue on the Integromat forum in Facebook.
Someone there might be able to assist you.
Create your formula field in Airtable first. Make sure that it results in any non-zero, non-error, non-false value. Your formula field can result in 1 or pretty much any other value that you’d like. Then copy and paste that formula into Integromat.
If you simply want to search for a checkbox field being checked, you can just use the name of your checkbox field (within curly brackets) in Integromat, since a checked checkbox field equals the value 1.
