Extract the value inside an expression from a certain layer
Hi guys! I have the following expression within the Source Text of different layers:
a= comp(“Data”).layer(“spreadsheet.csv”)(“Data”)(“Outline”)(“ID”)(“ID 0”)
b= comp(“Data”).layer(“spreadsheet.csv”)(“Data”)(“Outline”)(“Name”)(“Name 0”)
a + b
I am needing to display in a text layer of another composition the “b” value of one of the layers based on its index.
That’s possible? thanks!

There isn’t any way to externally access an expression’s internal local variables. The only way an expression can communicate with the outside world is by altering the value of property hosting the expression. However, it seems like your other expressions could get the value of b the same way your posted expression does (from the csv layer).

Thanks Dan for the quick response! no problem.
Yes, I can extract those values in the other composition, but I couldn’t alter the order without having to modify the expression. That’s why my idea of having a comp to establish the order of the results (layers index), and another to display them.
