thanks for your help. I partially solved the problem. The field is actually destinated for quantity values starting from 0.00, so should allow numbers such as:
1
2.1
0.1
216.09
12765.00
etc.
Your code actually works fine but accept only values like 20.00
(I know, my mistake. I didn't express myself correctly).
