Hello,

i have problem with some simbols in Math. I want to make a mathematical simbol for whole negative numbers. For whole numbers i use code "setZ". For whole negative nubers i tried to use code "setZ^-". But this code isn't correct. It shows an error (unexpected sign). Problem is when printing document, it also prints marks for errors. Can i use another code? Can i hide error marks?

Thanks,

Boštjan
