Hi Jimmi,
your parameter is being passed by value not object since it's a literal
value.
In your previous situation the function applied itself to a global variable
so this problem didn't occur.
Add a return statement to your function at the end:
function interpunk (par1):Void {
.....
return par1;
}
And call it like: outputString = interpunk (outputString);
Note however that reassigning parameter values is not considered good
practice, and you should avoid it.
