Use variable on own extension



I’m certainly asking a stupid question but i can’t find how to use a variable.

I’ve created a Block to connect the LCD.
I have then 6 Numbers.
When i’m compiling i get a error message saying that the variable is not declared.

Which is the correct way to use the variable ?



Enclose Parameter name in /*{}*/.
Example: (If Parameter name is Pin_1) /*{Pin_1}*/
