By using gb.language, you force a locale-aware comparison of the strings 
inside links. This locale-aware string comparison is implemented by first 
converting the strings into 32 bits Unicode, and that conversion apparently 
fails. What does the links array contain?

This is a little bug in addition optimization. Anyway, if you want to do 
arithmetic, do it on numbers, not on strings:

Maske.Index = CInt(wert[0]) - 1
