I'm far to be expert with Gambas but here I think I 
understand the cause of your problem.
In this instruction, Gambas try to evaluate first the 
expression between parenthesis, and it find a (string - 
number) expression, which is bad. I would rather write
Maske.Index = CInt(wert[0]) - 1

I think that the second experience fails because wert[0] is 
bigger than the acceptable max index value
