I'm sorry Jaanus. Read fully is one thing ... all understand is an other ;-) I didn't understand where I should put the code that you gave me. Yes, I executed it with PHP MyAdmin and now the field "duree" contains the good time. But if I add a new data into the list, it's always the same : in the list duree is ok, but in the database, the new entry is 00:00:06 (!). Then, I made again the UPDATE in the database and it corrected.
But it would be automatic .. Is it possible to add this code to the one you gave me for the calculation ?
For the custom query, it's a shame it doesn't seem to have more documentation about it. %s replace the nomtable.nomchamp ?
Thanks for your help and your patience !!!
