Sorry for my english, it is not good,
I want display qm as m3 with 3 in an higher position in the extra-fields, how can i do this?

Wolfgang,
Try either
m³
OR
m³

Include the ; as well.
I needed to put in m2 - HTML sup tags were stripped out. The character code above was accepted.

Regards
Mark


Edit: mmm at least you can see it works! Use the following code immediately after the letter M - without spaces between the characters:

& s u p 3 ;
OR
& # 1 7 9 ;

Hallo Marc,
that´s great, thank you.
