Hi Jeff , that was the trick .
Thanks for it.
Another fact :
I noticed that when filling a table the task is developed in a slow pace , and it get slow , step by step, when the rows are bigger .
i have a list with about 300 item an in each row 3 cell are fill
when I try with 30 , it run quick row by row , but when I run the whole list , the row pace is slower.
