But this does not work.

[if-item-field restzucker] is not accepted and [if item-field restzucker] is 
accepted by the interchange Server but it does not work

[/if-item-field] is not accepted by the Interchange Server.

Is an empty field like "" or is it like a NULL in a DB field ? And how can i 
test NULL in a if Statement ? 

i know the documentation but there is nothing to find about item's.
Perhaps its my bad english bu i must say that the docs and manuals are not 
really good for my taste. It could be because my i'm not good in PERL but i 
think interchange is for people without PERLknowlege.
