Got a basic question using Frogfm.
I'm using a textInput in a frame. 

But I would like when someone enters a value in the text input and presses Cast. It automatically adds that text. value to a cast compose function I have in a button.

So I have this text input. And when I press the button I want the Cast that textInput as {customValue} in the composer action.

it's impossible to do from the frame itself, or are you referring to Composer Form (a web page)?
