Use a composition to control some elements from one place
Create comp and call it [CONTROL ROOM]
Create any element, apply to it any control based on your needs from [Effects & Presets] > [Expression Control]
Color Control: Colors
Slider Control: I use it for opacity
Checkbox Control: ON / OFF
One the element opacity expression use this:
if (comp("CONTROL ROOM").layer("settings").effect("Lang | EN")("Checkbox")==1) { 100 } else { 0 };
For color, Apply [Fill] effect to the element and on the color use this
comp("CONTROL ROOM").layer("gaming-item-box").effect("Fill")("Color")
In the control room comp, show your selections
Add Text element with the following expression
(There is an alternative option here)
x = 0;
y = 0;
z = 0;
if (thisComp.layer("settings").effect("Payment | VISA")("Checkbox")==1) {x= "VISA"} else {x=""};
if (thisComp.layer("settings").effect("Payment | KNET")("Checkbox")==1) {y= "KNET"} else {y=""};
if (thisComp.layer("settings").effect("Payment | Cash")("Checkbox")==1) {z= "Cash"} else {z=""};
thisLayer.sourceText=x+y+z;
