Since liquidsoap does not actually allow mutation of variables, what you are

Maybe thinking of it this way, the error makes more sense.
Of course you didn’t use the result of source2.
The solution is to write an if else statement on one line.
This assigns the result to source if the condition passes, if not assign the
source to itself.
