Hi Graham, 161 means "error in source expression". Probably, it is saying that "if there is a folder (the defaultFolder)" can't be parsed into something that makes sense, which is correct because it is only the first part of an if-then-else control structure. If you remove the "if" then LiveCode can parse the string to true or false.
