You see, I don't know how/when/why/where " a certain condition does not occurs". Whatever decides this, can you not put a SetFocus on the required column from there (assuming it isn't decided in the valid event, which, as you say, won't allow setfocus)?

>At first I placed the code in the valid event but from it i could not use commands like setfocus etc. so I decided to set code inside the lostfocus event. I tried with valid but i got into great problems and I falled in the deepest desperation !! Maybe i should have tried a little bit more...but i had to put things at least as they were before I tried !!!

>>>if so i call a method (changevalue() ) is it right ? It happen that sometimes it does not test the value properly, it does not set properly the oldvalue when I enter the control. But it happens sometimes, the first time I enter the control, if I enter the control again and made a change it works fine.
