The sendMessage() function returns a 0-based index value. That is, the first
item in the list has an index of 0, then 2nd item an index of 1, ... 

What message are you sending in the getItem() function?

Were these calls derived from the win32lib? If so, the getItem() in that
library uses a one-based indexing scheme. So if you directly use the output
from the sendmessage in that getItem() you will always be off by one.
Instead use this...

 selected = sendMessage(idList,#188,0,0)
 item = getItem(idList,selected+1)
