When I replaced one switch list with a copy of the asset thumbnail, that displayed correctly. Misery.
The two original sessions still work fine. I've checked and rechecked spelling and punctuation several times, and will again tomorrow, but ?????
Welcome to the misery that is called "debugging HTML". Without seeing your HTML code I would suspect a spelling or punctuation error - yes I know you have checked that several times already but I too have been down that path only to later spot the error in a "DUH" moment.
