It works now. Due to the fact I have the table in buffering mode, I have to use REPLACE in for example the InteractiveChange event of the combo in order to see the value I change to in the combo window. Before I had "REPLACE mytable.numvalue WITH myArrow(This.value)" and the result was that the correct value entered into the table but the combo read value was wrong as explained earlier. Now, with BoundTo=.T., I tested "REPLACE mytable.numvalue WITH This.Value" and it works.

Thank you for keeping me testing.
