== Check, please! == 

 Can you do me a favour and check what I've done at  and ? I think you may have unintentionally botched things when you tidied the custom mask. ;) 

 Also, can you have a look at what I've been attempting at  and ? Clearly I'm doing something wrong because it doesn't work properly, but for the life of me I can't see what. 

 Thanks as always! )
