Hi Klas, thanks, it is much for me, I am not very expert.
I know that there is a way in JS that I can insert in the section STUFF of the field.
Please see also later topic where terveg give me some suggestions about this issue. Truerly, in this topic I had another problem that solved Randy.

Now problem is different, I need to insert data directly in uppercase. Have you any idea about istruction to insert ?
Many thanks, Louis
