Custom stack question…
I have adjustable height and width inputs.
I want to set a third variable based on the input of H and W.
Specifically the new variable is X = Width - (Height + 4).
How do I set this up in the pList. Is the Math the correct custom control and how would you setup the corresponding arguments and operators. Also, I don’t see ID reference under math. But, I need ID to place the result in my CSS variable that changes in relation to W and H.
