Ho do I make a function with if?

I make a function that contains if:

on init
	message(Add(1,2))
end on


function Add(x,y) -> output
	if x > 0
		output := x + y
	else 
		output := 0
	end if
end function

And I get the error message:

The definition of function Add needs to consist of a single line (eg. "result := <expr>") in order to be used in this context

You cannot call a function within another command like that, you need to store the output of it to a variable. So:

var = Add(x, y)
message(var)

Thank you!

on init
    declare $var
    $var := Add(1, 2)
    message(var)
end on



function Add(x,y) -> output
	if x > 0
		output := x + y
	else 
		output := 0
	end if
end function
