Hi Jan,
Thanks a lot for you answer, I think my file is a little old, so maybe some cell come from V7.
So for this case i will make a tool wich rewrite all cell considering their symbologie,properties...
Indeed I try the replace tool and you are right the three cell keep the same name.,but in my real file there is lot of more cells so i cannot let my users replace every group of cells one by one !
Again thanks
Regards
Arnaud
