I use the German version of OO. Since OO Version 1, I incorporated user-defined 
variables in the footer. That means, I defined a variable in the body of the 
document template thru the known process via the menu INSERT, e.g. LETTERNUMBER 
and gave it a value, e.g. "2007-nnn". Afterwards I set the cursor in the footer 
and chose "DISPLAY VARIABLE" "LETTERNUMBER", where it shows then "2007-nnn". So 
basically, my template has a field in the body of the document, where I can 
click and overwrite the number of the letter and automatically the value in the 
footer should be changed. This worked until I implemented the OO 2.3 version.
Now there's a bug showing a "0" as value in the footer regardless of the value 
I put in the "SET VARIABLE" "LETTERNUMBER" field. I could narrow this issue 
down to: variables with format "date" or "number" show correctly. Variables 
with format "Standard" or "Text" show "0". In the body of the document all 
tested variables show correctly. This affects not only 
the "simple" "SET/DISPLAY VARIABLE" but also the "INPUT BOX VARIABLE(?)" (in 
German called "EINGABEFELD").

I urgently need help on this, since my whole correspondence depends on it.

Thanks.
