Thank's.
This is working as shown in the exemple.
What are the usage of the other Var_x ?
I have tried to reproduce the query exemple

It does not work. I have set trigger onupdateuser . Are your query syntax compliant with sql syntax ? I am surprise to see two type of ' in this exemple and not table jointure between users and comprofiler for the id=user_id
Sorry for my poor knowledge.
