I have already managed to calculate dynamic “text” that shows a sum of “input 1” (currency) * “input 2” (procentege)

Now I am trying to make a new text field that sums the value of “Input 1!” - “the first textbox number value”

I Don’t know if I use the right terminal to explain this, but I want to basically calculate a sum of a variable text with another input.

Can I do this without a log-in user?
