[fusion-users] A phantom bug. Empty string to getElementById()

[Paul Spencer]

Ah yes!  This also affects Safari for those that are interested (the  
extra comma causes a javascript error in Safari).  I typically find  
this error by developing in firefox, testing in IE and it doesn't work  
(and no useful error messages), then testing in Safari where you do  
get a more useful error message.

Thanks for sharing the tip, Tómas

Cheers

Paul
